SAFETY
Meet with IEC1010 standard
Read the safety note before operation.
2-1 ．Do not input a limited value over-ranged.
2-2 ． The voltage below 36V is safety. To avoid electric shock, check whether the test lead s
are connected correctly, whether the insulation is good when measuring over 36 V DCV or
25 V ACV.
2-3 ．The test leads should be removed from the testing point when changing function and
range.
2-4 ．Choose correct function and range to avoid wrong operation.
2-5 ．Do not take measurement if the battery is not fit on or rear cover ked.
2-6. Do not input voltage when measuring resistance.
2-7. Remove the test leads and turn the power off before replacing battery or fuse.

1 ． If the resistance value is over the selected range value, “1 ” displays, thus, should se t to
a higher range. When measuring value is over 1M Ω，the reading needs a few seconds
to be stable. It's normal for high resistance measuring.
2．When input terminal is open-circuit, overload displays.
3．Before measuring in-line resistance, be sure that power is off and all capacitance are
released.

it means overrange, should set to a higher range.
2．Before taking measurement, LCD displaying might not be zero, the remaining will

3. If creeps seriously or the capacitor is breakdown when measuring large capacitance,
some digits are displayed and unstable.
