Introduction - Fluke 435-II Service Manual

4.1 Introduction

Procedures in this chapter should be performed by qualified
service personnel only. To avoid electrical shock, do not
perform any servicing unless you are qualified to do so.
The Fluke 434-II/435-II/437-II Three Phase Energy & Power Quality Analyzer (referred
to as Analyzer) should be calibrated and in operating condition when you receive it.
The following performance tests are provided to ensure that the Analyzer is in a proper
operating condition. If the Analyzer fails any of the performance tests, calibration
adjustment (see Chapter 5) and/or repair in a Fluke Service Center is necessary.
The Performance Verification Procedure is based on the specifications, listed in the
"Characteristics" Chapter 26 in the Fluke 434-II/435-II/437-II Users Manual. The Users
Manual can be downloaded from Fluke's website. Specifications are based on a one year
calibration cycle.
The values given here are valid for ambient temperatures between 15 °C and 35 °C.
Analyzer performance can be checked with single phase 50 and 60 Hz test signals such
as generated by a Calibrator Fluke 5700A.
The tests mainly verify accuracy and offset of voltage and current inputs.
Tests indicated with (*) are optional. They can be done to check if the Analyzer's
hardware (analog input channels) is OK. Bear in mind that the outcome of these checks is
rather influenced by hardware sanity than by Calibration Adjustment.
Accuracy of all other Analyzer functions is linked to input accuracy and is embedded in
the Analyzer's software. This link is tested extensively for each new software release.
This testing is done with the Fluke 6100A Electrical Power Standard and 6101A
Auxiliary units. This setup allows multiphase operation and direct testing of measuring
functions such as flicker, harmonics, interharmonics, fluctating harmonics, dips & swells,
unbalance and also compounds of these disturbances.
Fluke 6100A and 6101A are recommended for those who want to test all measuring
functions of Fluke 434-II/435-II/437-II.
Tests are done in V/A/Hz mode (unless indicated otherwise).
All indicated voltages and currents are rms values.
The Performance Verification Procedure is a quick way to check most of the Analyzer's
specifications. Because of the highly integrated design of the Analyzer, it is not always
necessary to check all features separately.
Always put the Analyzer in STBY (Stand By) mode before changing test leads.
Fluke 5700A has a toggle key OPR/STBY with function indication in the display.
Important: during all tests, signal must be applied to voltage channel A/L1. A/L1 is the
reference channel.
The verification procedure assumes that the test engineer is familiar with the operation of
Analyzer and Calibrator.
