1. INTRODUCTION
1.1 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.
1.2 Description
To install or replace the battery refer to section 3.1.
The PD240 is a convenient pocket-sized, battery powered proving unit that
produces a 240VDC output.
Any device used for voltage detection and for proving dead should be tested
before and after use to ensure the safety of the operative.
The PD240 is current limited to 2mA and is suitable for use with multimeters
and other voltage detectors that have an input impedance greater than
120kΩ.
The unit is actuated by microswitch when probes of a voltage detector are
inserted into the probe apertures on front face.

2. PRODUCT SPECIFIC SAFETY INFORMATION
2.1 Precautions
This product has been designed with your safety in mind, but please pay
attention to the following warnings and cautions before use.
Warning
Before use check the unit for cracks or any other damage. Make sure the
unit is free from dust, grease and moisture. Do not use if damaged.
Warning
Do not use the PD240 if the battery cover is not fitted.
Warning
Avoid severe mechanical shock or vibration and extreme temperature.
Warning
Remove the battery when not in use for an extended period to avoid
corrosion from leaking batteries.

3. OPERATION
3.1 Installing or Replacing Battery
Remove the rear battery cover by unscrewing the large plated screw at the
end of the cover. The screw is captive but once it is loose the battery cover
can be lifted clear.
Fit 1 new 6LR61 (MN1604, PP3) 9V alkaline battery.
Replace the battery cover by repositioning it onto the rear casing then
tighten the captive screw. Do not over-tighten.
3.2 How it Works
Always make sure the precautions applicable to the unit being tested are
observed.
Place the Hi probe of the unit under test into the left hand (+) socket until
it makes contact with the terminal. Place the Lo probe of the unit under
test into the right hand (-) terminal and press down firmly until the PD240
POWER indicator illuminates and the probe makes contact with the terminal.
Observe that the required indicators on the unit under test are illuminated,
then withdraw the probe from the right hand terminal, then the left.
If the PD240 power on indicator fails to illuminate, then consult the unit
under test (UUT) literature, to check the loading effect of the UUT upon the
PD240 output voltage (see figure 1).
If the unit under test should have no adverse effect upon the PD240 output
voltage then check the condition of the battery and replace if required.
