In working order.
PLEASE NOTE
The tester is over 30 years old and has not been calibrated for many years. As a result it should not be used for commercial purposes. However on a recent test it displayed exactly the same readings as a recently calibrated machine when used on the 20A Earth bond test function and the insulation test function (the 100ma earth test function showed a resistance approx 0.2 Ohms higher than the correct figure). As a result it may be useful for domestic non-commercial purposes.
The tester includes a 1500/3000V 'Flash Test' function but this is no longer required as part of the portable appliance test procedure.
