RP5 – G4 Meter Empty Capacitance Calibration (Figure 9)
a. Completely empty dewar.
NOTE: The meter must first be calibrated empty and then the
span must be set for your particular model. The unit must be
empty, warm, and dry for calibration.
b. Allow dewar to warm to room temperature.
c. Enter Calibration Mode
1. Press and hold the hidden calibrate button located on the
center of the meter face.
2. While holding the calibrate button, press and hold the
green operate button.
3. Continue holding both buttons until LED 1 and LED 8 al-
ternately flash. The meter is now in calibration mode.
4. Release both buttons.
d. Press and hold the hidden calibrate button for 3 seconds. LED
1 will flash for 3 seconds followed by a short pause.
NOTE: Step d must be performed within 45 seconds or calibra-
tion mode will exit.
e. If successful, LED 1 will flash again for 3 seconds and exit
calibration mode storing the new empty value.
f. If calibration is unsuccessful, multiple LEDs will flash. The
LEDs indicate what error has occurred (see Table 2).
