345 Calibration Manual Battery Charger/Power Adapter Note To accommodate connection to various line power sockets, the BE345 Universal Battery Eliminator is equipped with a male plug that must be connected to a line plug adapter appropriate for local use. Since the Charger is isolated, you can use line plug adapters with or without a protective ground terminal. The 230 V rating of the BE345 is not for use in North America.
Power Quality Clamp Meter Cleaning and Maintenance Cleaning and Maintenance WCaution To avoid damage to the Clamp Meter, do not apply solvents to the case. The Clamp Meter contains no user serviceable parts. Contact an Authorized Fluke Service Center for repair. See “Contacting Fluke”. Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Change the batteries when e appears. To change the batteries, see Figure 3: 1.
345 Calibration Manual fcs005.eps Figure 3. Changing the Batteries Verification Tests The following tests verify the functions of the Clamp Meter. If any of the verification tests fail, repair is necessary. For service, see Contacting Fluke.

Power Quality Clamp Meter Calibration Adjustment Calibration Adjustment Required Equipment The equipment listed in Table 2 is necessary to perform calibration adjustments. If the listed equipment is not available, substitute equipment items of equal specification. Table 2. Required Equipment Description Calibrator Model Number Specifications Fluke Model 9100 Universal Calibration System with power functionality, or Fluke 5520 or equivalent 0.4 to 600 V >0.25 % accuracy 4 to 1000 A >0.
345 Calibration Manual Once the screen in Figure 4 appears: 1. Press M twice. 2. Press E twice. The calibration mode screen appears, see Figure 5. fcs004.bmp Figure 5. Calibration Mode Screen Use the procedure in the next section to adjust the Clamp Meter.
Power Quality Clamp Meter Calibration Adjustment Calibration Adjustment Procedure Note Before calibration, ensure that the instrument clamp is degaussed up to a minimum of 1000 A. The calibration mode steps are listed in Table 3. Make sure the date and time are set to the current date and time. VOLTS CAL and AMPS CAL are independent, calibration constants are saved at the end of each section. Table 3.

345 Calibration Manual Calibration Verification Procedure The following sections detail the input levels used to check the Clamp Meter’s calibration. The specification is 100 % of the specified tolerance. Notes For regions with mains power at 50 Hz, inputs should be at 60 Hz. For regions with mains power at 60 Hz, inputs should be at 50 Hz. This avoids mains “beating” effect. Ensure instrument is degaussed up to a minimum of 1000A.
