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
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.

PD440S / PD690S
The PD440S and PD690S output a xed AC voltage for 5s before
the output voltage is reduced to 0V and the terminal output goes
into low impedance mode.
The PD440S xed output voltage is 440V AC 50Hz nominal.
The PD690S xed output voltage is 690V AC 50Hz nominal.
PD230SRD / PD440SRD / PD440SRDX / PD690SRD
The output voltage can be set to be to AC or DC mode using the
AC/DC output selection push button. The output voltage reduces in
steps over a period of 10s.
For example, the PD230SRD outputs voltage in the following steps:
230V for 4s, 120V for 2s, and 50V for 4s before the output voltage
is reduced to 0V and the terminal output goes into low impedance
mode.

the push button while
the proving device is not
being used
Output mode indications are as follow,
AC output mode - “AC” LED ON,
“DC” LED OFF
DC output mode - “DC” LED ON, “AC”
LED OFF
The LED will time out after approximately
10s. It is not necessary to wait for the
LED to time out before proving a voltage
indicator. If the LED is left to time out,
then a minimum of 3s is required before
pressing the button again or proving a
voltage indicator.
Changeoutput

The previous table shows the LED indicators for each PD
product type.
For example, the PD690SRD includes the following LED indicators-
690V, 440V, 230V, 120V, 50V.
Batterylowindication
All PD products support the battery low LED, which is illuminated
when the battery voltage is low.
PD440S / PD690S
On these PD products the “High voltage” LED is ON when the live
voltage is present at the voltage output terminals. If the loading
impedance of the voltage indicator (at the output terminals) is less
than 1kΩ then the “High voltage” LED will start ashing.
PD230SRD / PD440SRD / PD440SRDX / PD690SRD
On these PD products there are multiple LED to indicate the voltage
at the PD output terminals when a voltage indicator is under test
at the terminals. Refer to the graph of typical output voltage under
various voltage indicator load conditions on the specication page.
Also refer to the “PD Output voltages table” under section 2.2. The
LED indication will depend on the loading impedance of the voltage
indicator under test as well as the PD output voltage steps in the
“PD Output voltage table”. If the loading impedance of the voltage
indicator (at the output terminals) is less than 1kΩ then the “50V”
LED will start ashing.
VoltageOutputMode(AC/DC)
AC LED and DC LED indicate the PD output voltage mode.

3.3ProvingaTestLamp,VoltageTester/ Indicator,DMMetc.
Place one probe of the unit under test into the right hand socket
of the proving unit until it makes contact with the terminal. Place
the other probe into the left hand terminal of the proving unit and
gently press down. It is important to follow this procedure in order
to ensure PD output voltage is applied to the equipment under test
from the start of the PD output voltage test cycle.
The PD output voltage test cycle starts from when the voltage
indicator is applied to the left hand terminal of the PD.
On the PD440S and PD690S, the output voltage test cycle is
5s long.
On the PD230SRD / PD440SRD / PD440SRDX / PD690SRD, the
output voltage test cycle is up to 10s long.
At the end of these PD units’ test cycles, the output voltage drops
to 0V and the output goes into low impedance. For SRD and SRDX
versions, a minimum of 3s is required between tests.
Observe that the required indicators on the unit under test
illuminate, then withdraw the probe from the right hand terminal rst,
and then the left.
If none of the proving unit LED’s illuminate when performing the
above tests, check the condition of the proving unit batteries and
replace them if required (see section 4.1).
3.4TestLamp,VoltageTester/IndicatorCables
During the above tests, emphasis should also be placed upon the
exing of the UUT cable along its length, and particularly at the

9
entry points to the hand held elements, to conrm that the cable has
not fractured.
It may be necessary to perform this test a number of times as the
proving unit times out after 5s on the PD440S /PD690S and after
10s on the PD230SRD / PD440SRD / PD440SRDX / PD690SRD.
3.5 CALCHECK (PD440SRDXonly)
The CALCHECK feature may be used to check that a multifunction
tester, insulation tester or continuity tester is maintaining ongoing
accuracy between calibrations. There are two insulation test
resistance values, 0.5M Ω and 1M Ω. There are also two continuity
test resistance values, 0.5Ω and 1Ω.
One probe of the tester being checked should be placed on the
desired resistance value and the other probe should be placed on
the COM terminal, following the instruction manual for the tester
being used.
The CALCHECK feature is not designed to be used to check loop
testers, where the high test current will damage the proving device.
The CALCHECK (X models only) feature can be used as a regular
check that instruments are not drifting between calibrations.
Records can be kept using the CALCHECK Verication
Measurement sheet at the back of this manual. An initial
measurement can be taken soon after calibration and the results
recorded. Further checks can be made periodically, e.g. every
month, and the results also recorded on the sheet.
Further copies of the sheet can be downloaded from
www.martindale-electric.co.uk/manuals/.
