1. SAFETY INFORMATION
The following safety information must be observed to insure maximum
personal safety during the operation at this meter.
1) When measuring voltage ensure that instrument is not switched to the
current range, resistance range, diode and continuity range, capacitance range
or temperature range.
2) Use extreme care when measuring voltage above 50V. especially from
sources where high energy is existed.
3) Avoid making connections to "live" circuits whenever possible.
4) Before making resistance measurements, diode or continuity test,
capacitance test or temperature test, ensure that the circuit under test is
de-energized.
5) Always ensure that the correct function and range is selected.
6) Extreme care should be taken when using the instrument to conjunction with
a current transformer connected to the terminals if an open circuit occurs.
7) Ensure that the test leads and probes are in good condition with no damage
to the insulation.
8) Take care not to exceed the over-load limits as given in the specifications.
9) Before opening the cover of the battery cabinet to replace batteries.
disconnect the test leads from any external circuit, set the selector switch to
"OFF" position.
10) Keep the fingers after the protection ring when measuring through the
instrument lead.
11) Change the battery when the symbol “ ” appears to avoid incorrect data.
