24 Setting up the Analyzer MANUAL SETUP 1 Press the SETUP key and next Function key F4 - MANUAL SETUP to reach the MANUAL SETUP screen. 2 Use the up/down arrow keys to select one of the parameters listed below and then press ENTER to access the setup menu: 3 - Date, Time: use the arrow keys to select date, time, and date format. Press ENTER to confirm the selected date format. With a GPS receiver connected and F2 set to GPS ON, date and time are synchronized automatically. Time zone and daylight saving ON/OFF can also be set. Press F1 to access the GPS test menu that informs you about reception quality. Press Function key F5 - BACK to return to the previous menu. - Config: selection of 10 wiring (50/60 Hz power systems) configurations. Selection is done with F1, F2, F3 and the arrow keys. Then press ENTER to confirm and to enter a screen showing how to connect the Analyzer to the power system. When ready press Function key F5 twice to return to the SETUP entry screen. A step-by-step example on how to change the wiring configuration is given further on in this chapter. - Freq: adjustment of Nominal Frequency (50 Hz, 60 Hz or in Fluke 437-II also 400 Hz). Use the up/down arrow keys to select the Nominal Frequency. Press ENTER to confirm and Function key F5 - BACK to return to next higher menu. - Vnom: adjustment of Nominal Voltage. Use the arrow keys to select 100 V, 120 V, 230 V, 400 V or any other voltage. Press ENTER to confirm and Function key F5 - BACK to return to next higher menu. - Limits: see paragraph Limits Adjustments. - Clamp, A range, V scale: adjustment of the Analyzer to the characteristics of current clamps and voltage leads. The default selection is valid for the accessories as supplied with the Analyzer. The supplied voltage leads are 1:1 types; when using attenuating leads or a voltage transformer you must adapt the voltage scale accordingly (e.g. 10:1 for 10 times attenuation). Identically the current scale can be adjusted when using current converters in combination with current clamps. With the arrow keys you can customize voltage and current readout to any desired transformation ratio. Selection of Amps and Volt scaling is done with Function key F3 There are separate selection tables for the Phase and Neutral: Function key F4 is used for selection. Behind Amp clamp: you can select many Fluke clamp types. The Analyzer's sensitivity is adjusted automatically then. In case of clamps with more than one sensitivity the sensitivity of the Analyzer must be set to match with the clamp sensitivity (attainable under Sensitivity:). Behind Amp clamp: you can also select clamp sensitivity values such as 1 V/A, 100 mV/A and others. Sensitivity x10 increases amps sensitivity by 10 times. In this position the signal is AC coupled which means that DC signal components are blocked. Resolution is 10 times more with limited range. 24-7 MyFlukeStore Shop for Fluke products online at: www. .com 1.877.766.5412
