Warning

To avoid shock hazard, connect the instrument power cord to a power receptacle with earth ground.

AC Operation

Plug the line cord into the connector on the rear of the instrument. The instrument operates on any line voltage between 90 and 264V ac without adjustment, and at any frequency between 45 and 440 Hz. However, the instrument is warranted to meet published specifications only at 50 or 60 Hz.

DC Operation

The instrument may be operated from a DC voltage between 9 and 16 volts, consuming a nominal 4 watts. Connection is made at the rear panel ALARM OUTPUTS connector, pins (+) and (-). If both ac and dc sources are connected simultaneously, ac is used if it exceeds approximately 8.3 times dc. Automatic switchover occurs between ac and dc without interruption.

Warning

If voltages greater than 30V are to be measured, a safety ground must be attached to the rear panel ground connector when the instrument is operated from battery power.

Input Channels

The instrument provides one input (channel 0) on the front panel and 20 inputs (channels 1 through 20) through a connector on the rear panel. Channels 0, 1, and 11 can measure a maximum of 300V dc or ac rms; all other channels can measure a maximum of 150V dc or ac rms.
