Users Manual
Do not use in distribution systems with voltages higher than 660 V.

Use only recommended test leads.

Remove all power from the circuit under test and discharge circuit

capacitance before testing resistance or capacitor with the tester.
Results of measurement can be adversely affected by the

impedances of additional operating circuits connected in parallel
or by transient currents.
Before and after testing, confirm that the Tester does not indicate

the presence of a hazardous voltage. If a hazardous voltage is
shown on the display, remove power from the circuit under test or
allow the installation capacitance to fully discharge.
Do not disconnect the test leads before a test has been completed

and the test voltage at the terminals has returned to zero. This
ensures that any charged capacitance is fully discharged.
Use the guard terminal only as specified in this manual. Do not

allow other foreign objects to come into contact with the guard
terminals as safety may be compromised.
Remove the input signals before you clean the Product.

Use only specified replacement parts.

Repair the Product before use if the battery leaks.

Be sure that the battery polarity is correct to prevent battery

leakage.
Do not operate the Product with covers removed or the case open.

Hazardous voltage exposure is possible.
Have an approved technician repair the Product.
