2. Set the power supply to 7.0V, and verify that the low battery indicator goes off.
Reassembly
1. Press and release the hold switch (so the switch is down), and fit the button over the switch housing.
2. Set the mark on the function switch axis to the 200V AC position (horizontal position), see Figure 4.
3. Set the rotary switch on the front panel to the 200V position.
4. Reinstall the front panel, making sure the wires surrounding the PCB are not caught between the front
and back case halves.
5. Reinstall all but the battery cover screw (three screws) on the case back.
6. Reinstall the battery and battery cover. Then secure with the battery cover screw.
Performance Check
To perform a performance check on the meter, set up the test equipment as shown in Figure 1. Referring to
Table 2, set the 5700A calibrator controls as shown, and verify that the meter readings fall between the high
and low limits for each range.
