How to Measure Resistance

To use the DMM for resistance measurements, connect the resistor to the terminals labeled HI
(V Ω)and LO, select the resistance measurement function by pushing the [Ω] button on the
front panel as shown below in Figure 6.

Then connect the leads of the probes to the circuit in
parallel with the resistance in question (Figure 7).

How to Measure Frequency

To use the DMM for frequency measurements, connect to the terminals labeled HI (V Ω)and
LO. Select the frequency measurement function by pushing the Freq button on the front
panel as shown below in Figure 8. The meter is connected in parallel the same as taking a
resistance measurement (Figure 7).
