I. Overview
The PU690 proving unit is a compact and
lightweight voltage proving unit designed
for the compliance safety checking of 2
pole voltage testers prior to testing on a live
circuit.
It is a requirement of the Electrical Safety
Council and the HSE that every Electrician
proves their voltage testers before and after
confirming safe isolation. The PU690 is
also high and low Z impedance compatible
for proving voltage on mulimeters.

II. Safety Notices
1. Please carefully read and fully understand
the warnings and operating instructions
before use. If the instrument is used in a
manner not specified by the manufacturer,
the protection provided by the instrument
may be impaired.
2. If the proving unit appears damaged or is
not working properly, stop using it
immediately.
The operator’s safety is no longer ensured,
the instrument is to be put out of service
and protected against use. Safety may
be compromised if the instrument:
● Shows obvious damage.
● Does not carry out the desired measurements.
● Has been stored for too long under
unfavourable conditions.
● Has been subjected to mechanical stress
during transport.
3. Once the indicators on the voltage tester
have been visualised, please remove the
test probe from the right input first, and then
from the left.
