Symbols used on the instrument Caution: risk of electric shock Caution: refer to accompanying notes Equipment protected throughout by Double Insulation (Class II) NOTE THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS. RadioFans.CN 收音机爱 好者资料库 OPERATION Default Voltage measurement The 210170 will act as a default voltmeter (0 to 600 V a.c.) with any of the Insulation test positions selected. The Test push must not be pressed when making a voltage test. Note:- The 210170 is internally fuse protected to 500 V. For fuse protection with supplies above 500 V, use Fuse Probe Kit FPK5. 1.Select any Insulation test position with the rotary selector switch. 2.Carefully connect the test leads to the circuit under test. Do not press the Test push. 3.Read the voltage measurement from the voltmeter scale. 4.Carefully disconnect the test leads. Low Resistance measurement () 1.Select with the rotary selector switch. 2.Ensure that all test leads are clean and in good condition, and connect them to the isolated circuit under test. 3.Any pointer deflection indicates a live circuit, and testing should be aborted. 4.Press the Test push, and keep it pressed while turning the generator handle. 5.Read the measurement from the k scale. 6.Disconnect the test leads. Insulation Testing (M) Automatic circuit discharge is effective when the test button is released, and decaying voltage is indicated by the scale needle until the circuit is discharged. 1.Select M with the rotary selector switch. 2.Ensure that all test leads are clean and in good condition, and connect them to the isolated circuit under test. 3.Any pointer deflection indicates a live circuit, and testing should be aborted. 4.Press the Test button, and keep it pressed while turning the generator handle. 5.Read the measurement from the M scale. 6.Release the Test push and monitor any scale needle movement to confirm when any discharging voltage decays to zero. 7.When the circuit has discharged, disconnect the test leads. Refer to Safety Warnings before using the instrument MEASUREMENT SCALES RadioFans.CN 收音机爱 好者资料库 Using the Guard Terminal For basic insulation tests and where there is little possibility of surface leakage affecting the measurement, it is unnecessary to use the guard terminal. In cable testing, there may be surface leakage paths across the insulation between the bare cable and the external sheathing due to the presence of moisture or dirt. Where it is required to remove the effect of this leakage, particularly at high testing voltages, a bare wire may be bound tightly around the insulation and connected via the third test lead to the guard terminal G. The guard terminal is at the same potential as the negative terminal. Since the leakage resistance is effectively in parallel with the resistance to be measured, the use of the guard causes the current flowing through surface leakage to be diverted from the measuring circuit. The instrument therefore reads the leakage of the insulator, ignoring leakage across its surface.
