Basic steps oftheperformance verification test
Verification procedure consists following steps:
• range from 1TQ
• lta ranges kV
• range mA
• test points 10n, 50n, 100nF
Procedure
Following part describes procedure performance verification test.e.1 %
* Multifunction calibrator Meatest M-140, M142, Fluke 5500A similar with voltage range 1000
V. Performance verification may performed
after warm-up period i. Calibrator have temperature stabilize condition
at minimum hours before performance verification test started. minutes after switching on.2%.
Required equipment
