27 Performance Verification 3.1 Introduction Introduction Warning 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 433/434/435 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 4) and/or repair in a Fluke service center is necessary. The Performance Verification Procedure is based on the specifications, listed in Chapter 2 of this Service Manual. 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 5500A or 5700A. For Fluke 433/434 you can use a standard Calibrator (e.g. Fluke 5500A); for the more accurate model Fluke 435 you must use 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 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 433/434/435. 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 5500A has separate keys for STBY and OPR (Operate): OPR mode is indicated by a green LED in the OPR key. 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. 3-3

Use the Calibrator s field edit function (5500A: FIELD EDIT key, 5700A: AMPL/FREQ key) to adjust the Calibrator to an Analyzer readout of 400 V / 215 V. 17. Increase the frequency to 3 khz. Fluke 434: check for a readout of 378 V or more. Fluke 435: check for a readout of 204 V or more. 18. Set the Calibrator to STBY. Note: bandwidth will be slightly higher than in V/A/Hz mode because a low pass filter in the analog input channel is off during Transients mode. 3.9 Channel Isolation (*) This optional test verifies cross talk from voltage channels to current channels. Voltage channels normally get high voltages while the current channels have a sensitivity of a couple of volts. This way of testing verifies the most critical situation. Proceed as follows: 1. Connect the Analyzer s A/L1, B/L2, C/L3, and N voltage inputs with the HI output of the Calibrator. Connect the Analyzer s GND input with the LO output of the Calibrator. 2. Set all current channels to 1 mv/a, 400 A, 1:1 (SETUP menu, arrow and ENTER keys). Put the Analyzer in 3-phase WYE, 50 Hz, 400V, and V/A/Hz mode. 3. Short-circuit the four current inputs with a termination piece of 50 Ω or lower. Refer to Figure Set the Calibrator to 800 V, 50 Hz, and OPR. 5. Check that the readout on all current channels does not exceed 19 A (this includes the 5 A basic error of the current channels). 6. Set the Calibrator to STBY. 7. Disconnect all test leads. 3-17

45 Calibration Adjustment 4.1 General General Introduction The following information, provides the complete Calibration Adjustment procedure for the Fluke 433/434/435 Power Quality Analyzer (referred to as Analyzer). The Analyzer allows closed-case calibration using known reference sources. It measures the reference signals, calculates the correction factors, and stores the correction factors in RAM. After completing the calibration, the correction factors can be stored in FlashROM. The Analyzer should be calibrated after repair, or if it fails the performance test. The Analyzer has a normal calibration cycle of one year Calibration number and date When storing valid calibration data in FlashROM after performing the calibration adjustment procedure, the calibration date is set to the actual Analyzer date, and calibration number is raised by one. To display the calibration date and - number: 1. Press SETUP, then press F2 to see the Version & Calibration data (see Figure 4.1). 2. Press F5 to return to exit the Version & Calibration screen. Figure 4-1. Version & Calibration data. Note: The calibration date and calibration number will not be changed if only the Contrast Calibration Adjustment is changed 4-3
