To access the Menu, power-up the instrument, then press the center navigation button Below is a sample menu for a PosiTector Advanced Model: Memory Statistics Some buttons have a tick box to their Cal Settings right to indicate current status.
Typically a ratio between the accuracy of the standard and the accuracy of the Gage is sufficient. The PosiTector is shipped with a Certificate of Calibration showing traceability to a national standard.
For organizations with re-certification requirements, the PosiTector may be Measure the object. Page 11 2-point Calibration Adjustment Preferred method for very unusual substrate materials, shapes or conditions. Provides greater accuracy within a limited, defined range. Hold the button down to increase the rate of adjustment. On rough or curved surfaces a preferred method to iii is to take several readings on the known thickness and average the result. The Gage will wait 2 seconds between readings to allow the user to correctly position the probe on the surface.
After the last measurement the Gage will calculate and display the reading which represents the average of all the measurements taken. Preferred method for very unusual substrate materials, shapes or conditions. Provides greater accuracy within a limited, defined range. Select 2 Pt Adjust from the Cal Settings menu. Repeatedly measure the thinner item.
The Gage will wait for 2 seconds on the surface to allow the user to correctly position the probe on the surface. After the last measurement the Gage will calculate and display a thickness value which represents the average of all the readings taken using the factory calibration settings. Press to accept this value. When selected, the icon will appear and all calibration settings are "locked" to prevent further user adjustments. Uncheck to make further adjustments.
The icon will appear and the probe will only use the eddy current principle to shorten measurement time and extend battery life. N Lock is useful when measuring coatings on plated steel. N Lock makes the Gage measure the coating over the plating only. Select N Lock to measure over slightly magnetic substrates; i. Although the probe's magnet is used for the magnetic principle, it is also used in N Lock to magnetically saturate a slightly magnetic substrate and allow the eddy current principle to operate unhindered.
This is not recommended. It is often convenient to store a particular calibration adjustment before making another. Then, if you return to that part, the corresponding calibration setting can be restored. The PosiTector always displays the current calibration setting ex. Cal 3 in the upper right corner of the display. The setting called Cal 1 has unique features. It can be adjusted but never deleted, and is always made active with factory settings after a Reset.
Creates a new calibration setting using the next available number Maximum of This is indicated with the icon which appears at the bottom of the display. A warning message will prevent the creation of a new Cal Memory if a batch is open and has readings. Delete the batch first. Loads an existing setting. Use the Up or Down buttons to scroll until the desired setting appears, then press. A warning message will prevent the opening of a stored Cal setting if a batch is open and has readings.
Create a new batch first or open a batch containing no readings. Removes a setting completely from the list. That Cal number can be reused later with the New command. A setting cannot be deleted if readings have been stored into a batch using that calibration setting. Delete all readings in that batch first. Although Cal 1 cannot be deleted, the Delete function will return it to factory settings.
Reset menu reset restores factory settings and returns the Gage to a known condition. The following occurs:. This returns the Gage to a known, "out-of-box" condition and performs the same function as a menu Reset with the addition of:. Selects display brightness Sun, Normal or Night.
All settings will dim slightly after a period of no activity to conserve battery life. Press the Down button to brighten the display. Increases measurement speed for most probes. Useful for quick inspection or when measuring large areas with thick coatings where proper probe positioning is not critical. Reduced accuracy may be noted. By default, the PosiTector takes approximately 1 reading per second. Scan mode allows the user to take multiple readings in rapid succession 3 readings per second without lifting the probe.
Choose from 3 Scan modes:. When Memory is on, Scan measurement data is recorded. However, in Statistics and Limited Avg.
Note that performing a scan may reduce the life of the probe and is recommended for smooth surfaces only. For security purposes, the registration key is required to add the Gage to your free PosiSoft.
Ideal for right-sideup viewing when the sensors are pointed away from the user. All measurements are date and time stamped 24 hour format when stored into memory. It is therefore important to keep both the date and time current using this menu option. The battery state indicator icon is calibrated for the selected battery type.
No damage will occur if the wrong battery type is selected. Converts the display from inch to metric or vice versa.
Stored measurements in memory are not converted. Switching units will turn off Statistics, HiLo Alarm and closes memory. When selected, a icon and statistical summary will appear on the display.
Remove the last measurement by pressing the - button. Allows the Gage to visibly and audibly alert the user when measurements exceed user-specified limits.
When HiLo Alarm is selected, the current Lo setting is displayed. Alternatively, measure a coating with a thickness close to the required value and make final adjustments with the buttons.
Select NEXT to accept this value. The current Hi setting is now displayed. Follow the same procedure to adjust the Hi setting. The icon will appear on the display. Measurements will be compared to your defined HiLo limits. The Gage beeps if results are within those limits. A single low tone will sound if the reading is below the Lo limit, and a high tone if it is above the Hi limit. The PosiTector has internal memory storage for recording measurement data. Stored measurements can be reviewed on-screen or accessed via computers, tablets and smart phones.
Verification of Accuracy: as done by the user on known reference standards such as the included plastic shims or optional coated thickness standards. Probes are factory calibrated and perform an automatic self-check each time a measurement is taken. For many applications no further adjustment is necessary after a Reset pg.
Just check ZERO on the uncoated substrate, then measure. However, sometimes Gage readings can be influenced by changes in substrate shape, composition, surface roughness or by measuring in a different location on the part. That is why Cal adjustments are made possible. The XX symbol disappears whenever a Cal adjustment is made to e Gage. Where a Cal adjustment method has not been specified, use a 1-point method first.
If measuring the included shims on your surface reveals inaccuracies, use the 2-point method. Factory Cal settings can be restored at any time by performing a Reset pg. The XX symbol appears on the display whenever factory. Provides greater accuracy within a limited, defined range.
Measure a thin value often zero and a thicker value. These values should bracket your expected thickness range. Reset soft reset restores factory settings and returns the. It performs the same function as a menu Reset with the. Increases measurement speed for most probes. Useful for quick inspection or when measuring large areas with thick coatings where proper probe positioning is not critical. Reduced accuracy may be noted.
In ordinary operation, the PosiTector takes thickness measurements every 2 seconds when placed onto a surface. Normally, the user raises the probe after it has taken a single measurement and relocates it to a second location. Scan mode modifies this behavior in two ways. First, measurements are taken much faster.
Second, all measurements are recorded when memory is on. As the probe slides along the surface in scan mode, the PosiTector takes single measurements in quick succession. This may reduce the life of the probe. Recommended for smooth surfaces only. Allows the Gage to visibly and audibly alert the user when measurements exceed user-specified limits. The PosiTector has internal memory storage for recording measurement data. Stored measurements can be reviewed on-screen or accessed via computers, tablets and smart phones.
Measurements are date and time-stamped. Standard models store up to readings in one batch. Advanced models store , readings in up to 1, batches. The last 10 screen captures are stored in memory and can be accessed when connected to a computer.
