SCALING

Two resistors Ra and Rb may be fitted in order to alter the

full scale reading (F.S.R.) of the meter - see table.

The meter will need re-calibration.

Very low current consumption results in a long battery life and makes the DPM 950 ideal for portable equipment. For low light viewing,

a long life LED backlight is fitted. The meter is housed in a robust carrier which can be bolted in place or panel mounted using the bezel,

window and clips provided.

* Supply voltage 5V nom.

** To ensure maximum accuracy, re-calibrate periodically.
