Backlight
To verify that the backlight functions:
1. With the Product ON, push .
2. The backlight will come on. If it does not, repair is necessary. See “Contact
Fluke”.
Keypad Test
To verify that the keypad functions, turn ON the Product and push each button
separately. Each button push will turn on a display annunciator, and  will turn
on the backlight. If the buttons do nothing, repair is necessary. See “Contact
Fluke”.
Current Test
Before you do the current test:
1. Make sure that you have the necessary equipment. See Table 2.
2. Make sure the Product battery is good and replace it if necessary. See
“Battery Replacement”.
3. Warm up the Calibrator as necessary. Refer to its specifications.
4. Let the temperature of the UUT become stable to room temperature.
To do the current test:
1. Connect the Calibrator volts output and ground to the Product. See Figure 2.
2. Apply the input level for each step shown in Table 3.
3. Compare the indication on the Product display with the UUT reading limits in
Table 3.
4. If the display indication falls outside of the range shown in Table 3, calibration
adjustment or repair of the Product is necessary. See “Calibration
Adjustment”.
