The Meter measures resistance by sending a small current through the circuit. Because this current flows through all possible paths between the probes, the resistance reading represents the total resistance of all paths between the probes. The Meter's resistance ranges are 600. 0 , 6. 000 k, 60. 00 k, 600. 0 k, 6. 000 M, and 50. 00M. To measure resistance, set up the Meter as shown in Figure 5. The following are some tips for measuring resistance: · · The measured value of a resistor in a circuit is often different from the resistor's rated value. The test leads can add 0. 1 to 0. 2 of error to resistance measurements. To test the leads, touch the probe tips together and read the resistance of the leads. If necessary, you can use the relative (REL) mode to automatically subtract this value. The resistance function can produce enough voltage to forward-bias silicon diode or transistor junctions, causing them to conduct. If this is suspected, press C to apply a lower current in the next higher range.

Measuring Resistance 19 80 Series V Users Manual Using Conductance for High Resistance or Leakage Tests Conductance, the inverse of resistance, is the ability of a circuit to pass current. The Meter's 60 nS range measures conductance in nanosiemens (1 nS = 0. 000000001 Siemens). Because such small amounts of conductance correspond to extremely high resistance, the nS range lets you determine the resistance of components up to 100, 000 M, 1/1 nS = 1, 000 M. To measure conductance, set up the Meter as shown for measuring resistance (Figure 5); then press Cuntil the nS indicator appears on the display. The following are some tips for measuring conductance: · High-resistance readings are susceptible to electrical noise. To smooth out most noisy readings, enter the MIN MAX recording mode; then step to the average (AVG) reading. There is normally a residual conductance reading with the test leads open. To ensure accurate readings, use the relative (REL) mode to subtract the residual value. · 20 Making Measurements Measuring Capacitance WCaution To avoid possible damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the dc voltage function to confirm that the capacitor is discharged. The Meter's capacitance ranges are 10. 00 nF, 100. 0 nF, 1. 000 µF, 10. 00 µF, 100. 0 µF, and 9999 µF. To improve the accuracy of measurements less than 1000 nF, use the relative (REL) mode to subtract the residual capacitance of the Meter and leads.
