3.3 Battery Voltage Measurement
The amount of remaining battery charge can be estimated by checking battery voltage
(Vbat). This is done by connecting an external voltmeter with internal resistance of greater
than 1M_ to the battery measurement sockets (see Figure 1-1, no. 10).
If Vbat _ 12V, the battery is operating normally. If Vbat _ 11V, the battery is LOW. If
Vbat_10.5V, the battery is fully discharged.
Power supply: 100-240 VAC, 45-65 Hz, 30 VA.
Battery: rechargeable; 12V/1.2Ah DC. Allows 20 minutes work when fully charged. Long-term storage
of the battery is according to the following:
Accuracy: The EDL175 accuracy is a function of the accuracies of the PM175, the clamps and the
external transformers (PT and CT). Most of the EDL175 measurement error is due to the latter two
