Page 9 Basic Maintenance Warning To avoid shock, remove the test leads and any input signals before opening the case or replacing the battery or fuses. Opening the Meter Case Caution To avoid unintentional short circuit, always place the uncovered meter assembly on a protective surface. When the case of the meter is open, circuit connections are exposed. To open the meter case, refer to Figure 1A and do the following: 1. Disconnect test

Page 10 Testing Fuses To test the internal fuses of the meter: 1. Turn the rotary selector switch to the Ω position. 2. To test FS1, plug a test lead into V ΩHz input terminal and touch the probe to the mA input terminal. The display should indicate between 0.0 to 0.2 Ω. FS1 (1A 600V - Bussmann BBS-1 recommended). If display reads higher than 0.2 Ω, replace the fuse. Fuse Replacement Refer to Figure 1B to replace the fuse: Figure 1B Use only a fuse with the amper

Page 11 Performance Tests The following performance tests verify the complete operability of the meter and check the accuracy of each meter function against the meter’s specifications. Accuracy specifications are valid for a period of one year after calibration, when measured at an operating temperature of 18ºC to 28ºC and at a maximum of 80% relative humidity. To perform the following tests, it is not necessary to open the case; no adjustments are necessary. Merely make the re

Page 13 Testing the Capacitance Function The meter measures capacitance by charging the capacitor with a known direct current, measuring the resultant voltage, and calculating the capacitance. If the same capacitance is measured on an impedance bridge, a different reading may result. This variance is likely to be greater at higher frequencies. To verify the accuracy of the capacitance measuring function, do the following: 1. Apply the capacitor to the V ΩHz and COM inputs on the
