2. INTRODUCTION

2.1 Inspection

Examine the shipping carton for any sign of damage. Inspect the
unit and any accessories for damage. If there is any damage then
consult your distributor immediately.

2.2 Description

Voltage Indicating LEDs
Calibration card
(PD440SRDX only)
The PD230SRD / PD440S / PD440SRD / PD440SRDX / PD690S /
PD690SRD are portable battery powered proving units for testing of
contact type voltage detectors or other units with voltage detection
capability, e.g. multimeters or multifunction testers. The table below
shows the differences in the output voltage for each model.
After the voltage detector probes are pushed down onto the
Proving Device (PD) unit output voltage terminals, the PD unit
outputs voltage level(s) for period(s) indicated in the table before
the voltage drops to 0V and the terminal's output goes into low
impedance mode.
