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 shock, always place the uncovered Meter assembly on a protective surface. When the case of the Meter is open, circuit connections are exposed. -
Page 12: Testing Fuses
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 VΩHz input terminal, and touch the probe to the A input terminal. The display should indicate between 0.0 to 0.2Ω. -
Page 13: Performance Tests
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 18°C to 28°C and a maximum of 80% relative humidity. -
Page 14: Testing The Voltage Function
Page 12 Testing the Voltage Function To verify accuracy in the AC and DC voltage ranges, do the following: 1. Turn the rotary switch to “V ” position. 2. Connect the Calibrator to the VΩHz and COM inputs on the Meter. 3. -
