MARTINDALE PD240 Proving Unit Instruction Manual

MARTINDALE PD240 Proving Unit

INTRODUCTION

The PD240 Proving Unit is designed to provide a low voltage output for testing multimeters, clamp meters, and other voltage indicators. This product is intended for use by competent individuals who understand the risks associated with working with voltages exceeding the extra low voltage (ELV) limit of 50VAC RMS or 120V DC.

PRODUCT-SPECIFIC SAFETY INFORMATION

Precautions

• Always read and understand the instruction manual before use.
• Ensure the unit is in good working order before use and that there are no signs of damage to it. Do not use if damaged.
• Use other applicable safety measures such as protective gloves and goggles when necessary.
• Avoid using the unit in damp or wet conditions.
• Disconnect the unit from the supply before changing batteries.
• 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.
• Do not use the PD240 if the battery cover is not fitted.
• Avoid severe mechanical shock or vibration and extreme temperature.
• Remove the battery when not in use for an extended period to avoid corrosion from leaking batteries.
• Do not short the output terminals.
• Do not use in wet conditions or with wet hands.
• If this equipment is used in a manner not specified by Martindale Electric, the protection provided by the equipment may be impaired.

OPERATION

Installing or Replacing Batteries

The PD240 Proving Unit operates from two 1.5V LR03/AAA batteries. To install or replace batteries:

1. Unlock and remove the battery compartment cover located on the back of the unit.
2. Insert two new batteries, ensuring correct polarity is observed.
3. Replace the battery compartment cover and lock it in place.

• 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.

How it Works

• The PD240 Proving Unit generates a low voltage output of either 50V AC RMS or 120V DC that can be used to test multimeters, clamp meters, and other voltage indicators. The output voltage is indicated by the green LED light.
• 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.
