Cleaning the Tester
To avoid electrical shock or damage to the tester, never allow
water inside the case. To avoid damaging the tester's case,
never use solvents on the tester.
If the tester requires cleaning, wipe it down with a cloth that is lightly dampened with water or a
mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or methanol-based fluids
when wiping down the tester.
Required Equipment
The following equipment is required for performance tests and calibration adjustments:
•
Fluke 5500A Multi-Product Calibrator, or equivalent (DC voltage range: 0 to ±1020 V,
AC voltage range: 1 mV to 1020V 10 Hz to 500 kHz, sine)
•
Small, insulated, Phillips screwdriver
•
Fluke 87 Digital Multimeter (maximum DC voltage = 1000 V ± (0.05%+1), maximum
AC voltage= 1000 V ±(0.7%+2) )
Performance Tests
Use the following procedures to verify the tester's performance.
Testing the Voltage Function
If the tester fails the voltage test, perform the calibration adjustment described under "Calibration
Adjustment"; then retest all of the voltage functions. If the tester continues to fail, return it to
Fluke for service.
Test the voltage function as follows:
1. Set the calibrator to 199 V dc. Apply this voltage to the tester to verify that the 220 V dc
range LED is on.
2. Apply 190 V dc to the tester. Verify that the tester's 220 V dc range LED is off.
3. Apply each nominal voltage and frequency as listed in Table 2. Verify that each
corresponding LED turns on.
