Caution
To avoid possible damage to the Meter or to the equip-
ment under test, check the Meter's fuses before measur-
ing current. Use the proper terminals, function, and range for
your measurement.
Never place the probes across (in parallel with) any
circuit or component when the leads are plugged into the
current terminals
.
When measuring current, the Meter acts like an impedance
such as 0.01Ω at AC/DC A (approximately 1.5KΩ at DC µA) in
series with the circuit.
This loading effect of the Meter can cause measurement
errors, loading effect error, especially in low impedance
circuits.
For example : To measure a 1Ω impedance circuit will cause
a –1% measuring error. The error percentage of the loading
effect of the Meter is expressed as following :
