Backlight Test
To Test the Backlight, press Q and verify that the backlight comes on.
Keypad Test
To test the keypad, turn the Meter to Ω E and push each button separately. Each button push should cause the Meter
to beep and activate a display annunciator.
Reset the Meter by turning it Off and then back to an On position.
Preparing for the Performance Tests
XWWarning
To avoid possible electric shock or personal injury:
• Do not perform the following procedures unless qualified to do so. Some
procedures involve the use of high voltages.
• Before handling the test connections and in between tests, make sure
the calibrator is in standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment (refer to Table 2).
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the UUT to stabilize at room temperature (23 °C ± 5 °C [73 °F ± 9 °F] ).
4. Check the Battery, and replace it if necessary. Refer to “Replacing the Battery”.
To verify the accuracy of the Meter functions, do the following:
