Martindale PD690S Proving Unit 690V AC
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.
With all the benefits of the industry standard Martindale PD440 and PD690 proving units, the new S models come in an overmoulded low profile case with magnetic hanger. They are fast and easy to use, instantly supplying the full test voltage for both high and low impedance voltage indicators, test lamps and meters.
The SX Series have a unique CALCHECK feature making it easy to verify the insulation and low resistance ranges on 18th Edition multifunction testers, wherever you are working. In addition, the new SX models have stepped voltage LEDs with thresholds matched to most voltage indicators and two pole testers.
Martindale PD690S Comes Supplied With:
- MG3 magnetic hanger
- 6 x 1.5V AA alkaline batteries
- Instruction manual
- Ideal for proving low and high impedance voltage indicators, test lamps and two pole testers
- Includes MG3 high strength magnetic hanger
- Colour coded for voltage output (440V and 690V)
- Tough overmoulded low profile design
- Long battery life with low battery indicator and auto power off
Additional features PD440SX and PD690SX

Delivery Notices (Updated March 29th 2021)
During the current situation surrounding the effects of the Coronavirus pandemic, logistics from every company are under immense pressure to deliver goods on time.
Coupled with manufacturers on reduced output due to more stringent working practices and a global shortage of component parts to supply UK manufacturing, we have taken the decision to temporarily limit our services rather than let our customers down amid these unprecedented circumstances.
We hope you will understand our position on this and we apologize unreservedly for the inconvenience we know it will cause.
Please note that ALL orders placed before 3:00pm are shipped same-day (subject to stock and any additional services required).
The stated transport times above have some scope for adjustment built-in for the Covid-19 situation. Carriers themselves also have their own extended workload and limitations at this time which are unfortunately beyond our control.
Easter is always a busy time for suppliers and distributors alike, please bear in mind that we will be away from the office from 17:00 Thursday 1st - 08:00 Tuesday 6th April.
This will likely further impact expected lead times on goods arriving and leaving our premises, we advise you to place your order in good time to negate delays as far as possible.
We apologise for the added disruption that this period is likely to bring.
Orders requiring calibration
Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received PM and requiring
calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch

Predicted delivery times are based on regular trading days Monday to Friday. Public holidays, bank holidays and weekends are outside the usual scope
of our dispatch and subject to activities/holidays of our carriers and therefore may incur additional days lead time to your order.
