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
PD430 & PD440
The PD430 & PD440 are portable battery powered proving units for
the testing of contact type voltage detectors up to 440V.
The PD430 is a dual voltage proving unit which generates 50V at
50Hz for 3 seconds and then generates 440V at 50Hz. The PD440
generates 440V only at 50Hz.
PD690 & PD700
The PD690 & PD700 are portable battery powered proving units for
the testing of contact type voltage detectors up to 700V.
The PD700 is a dual voltage proving unit which generates 50V at
50Hz for 3 seconds and then generates 700V at 50Hz. The PD690
generates 700V only at 50Hz.
PD710
The PD710 is a portable battery powered proving unit for the testing of
contact type voltage detectors up to 700V.
The PD710 generates 700V DC only.
3. OPERATION
Caution
Always make sure the precautions and limitations of the unit being
tested are observed. If necessary refer to the specification of the
unit being tested.
Also refer to the graph of typical output voltage under various load
conditions at the rear of these instructions.

3.2 Using the External Power Socket
An external power jack socket is provided, allowing the use of an
external 12V DC power source instead of the internal batteries.
Remove the rubber shroud from the jack socket access hole, and
plug in a 12V DC source (2A minimum) using a 2.5mm jack plug
(centre positive).

2.3 Accessories
All units come with the following accessories:
6 x 1.5V AA alkaline batteries
Instructions
Accessories not included:
PSUPD230 - mains powered 12V DC power supply
PSUHPAT12 - 12V DC in car fused charger adaptor
2.4 Battery Installation
Refer to Section 4.1 (Battery Replacement) for the battery installation
instructions for all units.

If internal batteries are fitted they will be disconnected by the
insertion of the jack plug. If however, the internal batteries are not
the intended primary power source, it is advisable to remove them
to prevent damage from leaking batteries.
It is advisable to replace the rubber shroud after use to prevent the
ingress of dust and moisture.
Two suitable units available from Martindale Electric for providing
external power are the:
PSUPD230, a mains powered, 12V DC power supply;
PSUHPAT12, a12V DC in car fused adaptor.
