Calibration; One-Point Calibration (Zero); Two-Point Calibration - Check-line DC**-3000PS series Operating Instructions Manual

6.0 MANAGING SINGLE AND STATISTICAL VALUES
The 3000PS gauge is provided with online
statistics. The statistical values are re-
calculated and displayed in the two bottom
lines after every measurement.
statistical values calculated by the 3000PS
gauges are:
N: Number of measured values
x: Average of measured values
s: Standard deviation
Max: Maximum single value of the measurement series
Min: Minimum single value of the measurement series
Note: The DCFN-3000PS can store a total of 80 readings combining the F-mode
N-mode, not 80 readings in each mode (160 total).
6.1 Selecting which statistical values will be displayed.
1. Press DOWN repeatedly until Options appears on the display.
2. Press OK.
3. Press DOWN until On-Line Statistics appears on the display.
4. Press OK.
5. Press DOWN to select either Maximum and Minimum or Mean and Std
Deviation for display.
6. Press OK to confirm your selection.

CALIBRATION

4.1 Measuring Using Factory (Works) Calibration
1. Press DOWN. Calibration appears on the display.
2. Press OK. Zero Setting appears on the display.
3. Press DOWN repeatedly until Delete Calibration appears.
4. Press OK. Works Calibration Activated appears briefly, then the start screen
with - - - -. You can now carry out the measurement.
4.2 One-point calibration (zero procedure)
This procedure requires an uncoated test object having similar dimensions and
material properties to those of the coated object to be measured.
1. Press DOWN. Calibration appears on the display.
2. Press OK. Zero Setting appears.
3. Place the Measuring Sensor (item G, page 3) on the test object at a right angle.
Press gently and hold until chime sounds, then lift up. Repeat several times.
4. Press OK. Zero has been set appears briefly on the display, followed by the
start screen with - - - -. You can now carry out the measurement.
4.3 Two-point calibration (using calibration foil)
As with Zero setting, this procedure requires an uncoated test object having similar
dimensions as the coated object that will be measured. Choose a calibration foil that
is closest to the expected coating layer thickness.
1. Carry out a zero procedure (see section 4.2).
2. Press DOWN. Calibration appears on the display.
3. Press OK. Zero Setting appears.
4. Press DOWN again. Foil Calibration appears.
5. Press OK. Place probe on foil. Standard appears.
6. Put the measurement foil on the uncoated test object and place the probe
repeatedly on the foil.
7. Press UP or DOWN until the displayed value agrees with the thickness value of
the calibration foil.
8. Press OK. Calibration has been set appears briefly, then the start screen with
four dashes - - - - appears. You can now carry out the measurement.
