FEATURE ELECTRICAL SAFETY
PROVING UNITS VERIFY SAFETY AND CALIBRATION IN ONE N
ow available from Martindale Electric are the latest PDS and PDSX Series of proving units.
Smaller, lighter and with new options for calibration checking test equipment, Martindale’s next generation PDSX proving units, enable contractors and maintenance teams to safely and simply prove the operation of voltage indicators, two pole testers and test lamps plus common 18th Edition tester functions. The PDSX Series includes an additional
CALCHECK feature for verifying the calibration consistency of multifunction installation testers providing confidence in the performance of all essential test equipment before and after measurement. CALCHECK makes it easy to verify the
insulation and low resistance ranges on 18th testers on-site, making it ideal for identifying potential calibration issues with test equipment prior to certifying a new wiring installation or carrying out a condition report. This is a valuable procedure recognised by electrical contractor assessment bodies to ensure reliable results and avoid unnecessary and expensive retests. Safe electrical working requires the use of a
voltage indicator that has been proven with a suitable proving device before and after use to ensure the instrument is working correctly in accordance with the Electricity at Work Regulations. Having de-energised and locked off a circuit prior to maintenance, it is essential to prove your tester before and after you have proved the circuit to be dead in accordance with
safe isolation procedures. The easiest and safest solution is to use a proving unit matched to the voltage indicator which can supply the full voltage range of the tester wherever you are working. Fast and easy to use, immediately supplying the
full test voltage on contact, Martindale’s new proving units are suitable for proving two pole voltage indicators, and test lamps with voltage measurement ranges up to 440V and 690V. Featuring all the benefits of the industry standard Martindale PD440 and PD690, the new PDS and SX series of proving units come in a durable over moulded, low profile case, and include an MG3 detachable magnetic hanger, which enables the unit to be positioned securely nearby, ideal where space is limited or access difficult. For simplicity the S Series have a single voltage
output while the SX Series output voltages are stepped with individual LED indicators for each voltage level from 50V to 690V. The voltage levels are matched to common two pole tester thresholds, ideal for identifying potential voltage tester calibration issues. For added ease of use, the
new units are also colour coded so that the voltage output can easily be identified and matched to Martindale voltage indicators and test lamps which share the same colour coding.

BAXI HEATING CHOOSES MARTINDALE FOR ELECTRICAL SAFETY
Martindale Electric has supplied Baxi Heating with testers for checking appliance wiring and earthing, together with locking off devices to ensure circuits can be safely isolated before carrying out any work. The tools keep their gas service engineers safe when installing and servicing heating equipment and are essential for achieving compliance with the latest Gas Safe Register guidance TB118 2018. The changes mean new test procedures are now required to keep service
engineers safe from electrical hazards. In addition to carrying out safe isolation procedures to prove that circuits are dead and locked off, the new guidance now requires verification of mains earthing. Founded in 1866, Baxi Heating is a part of BDR Thermea, one of
Europe’s largest manufacturers and distributors of domestic and commercial water and space heating systems. As an industry leader with more than 6,400 service engineers worldwide, Baxi Heating is at the forefront of improving gas service and installation engineers’ safety in the field, in accordance with the latest changes to TB118. After researching the market, Baxi Heating has provided 250 of its
trainers and engineers with a range of Martindale Electric equipment, which includes the EZ650 earth loop and polarity checker for socket and spur testing. The EZ650 simplifies the process for identifying a satisfactory earth, by combining a basic socket tester with an earth loop check that

uses clear red / green LEDs, making it easy to interpret the results and see whether the earth loop value is within acceptable limits. The EZ650 socket and loop tester can be used on both 13A sockets and fused spurs to quickly identify a hazardous earth before starting work. This approach offers a simple solution to complying with TB118. For more information, please contact Martindale Electric on 01923
