Getting Started 3.1 Main Board Power Jumpers

SECTION 3 GETTING STARTED 3.1 Main Board Power Jumpers

Caution: The meter has no power-on switch, so it will be in operation as soon you apply power.

The meter can be configured to operate on 115VAC or 230VAC by the proper combination of the soldered wire jumpers that are located on the printed circuit board. The meter is set at the factory to be powered by the voltage specified at the time of ordering. The same transformer is used for either configuration, so all you need to do is to select the jumpers as described in this section.

Important: These changes must be performed by a qualified technician.

Note ☞ To change the Factory preset jumpers, do the following steps:

Disconnect the power from the unit before proceeding.

1.Remove the main board from the case. Refer to Disassembly/Assembly Section 3.8.

2.Locate the solder jumpers W1, W2, and W3 (located near the edge of the main board alongside the transformer).

3.If your power requirement is 115 V ac, solder jumpers W1 and W3 should be wired, but jumper W2 should not. If your power requirement is 230 Vac, solder jumper W2 should be wired, but jumpers W1 and W3 should not.
