About Digital Multi-meter
◆
Before using, you must select the right input jack, function and range.
◆
Never exceed the protection limit values indicated in specifications for each range of measurement.
◆
When the tester is linked to a measurement circuit, do not touch unused terminals.
◆
Do not measure voltage if the voltage on the terminals exceeds 660V above earth ground.
◆
At the manual range, when the value scale to be measured is unknown beforehand, set the range
selector at the highest position.
◆
Always be careful when working with voltages above 60V DC or 40V AC, keep fingers behind the
probe barriers while measuring.
