Continuity Test
Range Resolution Overload Protection
0.01 Ω 1000V
• Open circuit voltage approximate -1.2V.
• The buzzer does not sound when the test resistance is >60 Ω
• The beeper sounds continuously for open circuits and if test resistance is ≤40 Ω
Diode Test
Range Resolution Overload Protection
0.0001 V 1000V
• Open circuit voltage approximate 2.8V.
• A good silicone junction drops between 0.5V and 0.8V
• True rms are valid from 10% of range to 100% of range
• AC crest factor can be up to 3.0.
• A residual reading of 80 digits with test leads shorted, will not affect stated accuracy.
• When frequency is lower than 100kHz, the accuracy guarantee range 10% -100%
• For AC+DC measurement, add (1%-35 digits) of reading based on above table.
• When the measured current is ≤5A, continuous measurement is allowed.
• When the measured current is between 5A-10A, continuous measurement must
be ≤10 seconds and interval more than 15 minutes.
