If the Meter Does Not Turn On

Use the following steps to help solve problems encountered when turning on the Meter.
1. Verify the power switch is in the "On" position.

the Meter.
3. Make sure the power source the Meter is plugged into is energized.
4. Ensure the power line voltage of the Meter is set to the proper value for your country.
See the "Fuse Replacement" section earlier in this chapter for instructions on
changing the voltage setting.
