Warnings and Precautions

The AC68C Digital Clampmeter conforms to EN61010-2-032,

EN61010-1, CAT III- 600V, class 2 and pollution deg. 2; and

UL3111-1. It is recommended for use with local level power

distribution, appliances, portable equipment, etc., where only

smaller transient overvoltages may occur, and not for primary

supply lines, overhead lines, and cable systems.

•

Do not exceed the maximum overload limits per function

(see specifications) nor the limits marked on the

instrument itself. Never apply more than 600 V dc / ac

rms between the test lead and earth ground.

•

Inspect the DMM, test leads and accessories before

every use. Do not use any damaged part.

•

Never ground yourself when taking measurements. Do

not touch exposed circuit elements or test probe tips.

•

Do not operate the instrument in an explosive

atmosphere.

•

Exercise extreme caution when: measuring voltage

>20 V // current >10 mA // AC power line with inductive

loads // AC power line during electrical storms //

current, when the fuse blows in a circuit with open

circuit voltage >600 V // servicing CRT equipment.

•

Always measure current in series with the load – NEVER

ACROSS a voltage source. Check fuse first. Never

replace a fuse with one of a different rating.

•

Remove test leads before opening the case.
