Under Earth Continuity test, solid “

within 0.01

“×” displays for the range between “0.51

3.2
With Earth Continuity, Insulation Resistance tests all completed, the
Meter would show “FAIL”if one of these items displays “×”If the meter displays
“PASS” and at the same time one “

4. Testing a Class 1 Equipment
Plug the appliance into the mains socket (A). Plug the earth test lead into the rear socket (F). Connect the
earth test crocodile clip/probe to an exposed earthed metal part on the appliance. If there is a switch on the
appliance, ensure it is in the “on” position. Press Class 1 button the earth test will be carried out, if the test
result is a SOLID PASS, this indicated the result is less than 0.1 of an ohm. However if the PASS is
FLASHING this indicates the result is between 0.1 to 0.5 of an ohm, this could be due to the length of the
lead connected to the appliance. If the appliance under test has only a short lead then this result must be
investigated. The Insulation Test will follow.
If the result is a FAIL on the earth, ensure that you are not connected to a piece of metal which has
