WARNING: Make certain the external power source is off before connecting the resistance to be measured
2. Set the DC-AC-OUTPUT switch to the DC position and
the RANGE switch to the 250V position.
3. Adjust the DC power source for a full-scale reading of 250 volts with the meter leads connected across resistor
Rl. Make certain not to overload the meter.
4. With the high value resistor to be measured connected in series with resistor R1, as shown in figure 3, read the
voltage on the meter; then refer to table 4 to obtain the corresponding resistance value.
