Remove calibrator and apply a separate 2 Ω resistor for the following step.
20.00 Ω
The following procedure verifies the minimum current for a 2-Ω Load in continuity
function.
1. Connect a 2-Ω resistor and DMM to the UUT as shown in Figure 9.
2. Set the DMM rotary function switch to the mVDC function.
3. Set the UUT rotary function switch to the Ω function.
4. Press the T key and record the DMM voltage reading.
5. Using Ohms Law (V = I x R where: V = Voltage, I = Current, and R =
Resistance), calculate the current through the 2-Ω resistor.
6. The current should be greater the 200 mA.
