Voltage Tests (V) - Megger BMM500 Serie Guia Del Usuario

Operation
current and wide measurement range(0,01kΩ
to 10000kΩ) make the resistance range very
useful for general purpose testing.

Voltage Tests (V)

If >1V a.c. or d.c. is present at the terminals the
measured voltage is indicated on the display.
The voltage display will function within
specification even if the fuse has blown.
If the voltmeter operation is in question, test the
voltmeter on a known source.
1. Set the selector switch to V.
2. Connect the test leads.
3. After a short settling time, the reading will
be displayed automatically.
Millivolt Tests (mV)
The measured a.c. or d.c. voltage is indicated
on the display.
1. Set the selector switch to mV.
2. Select either ac or dc mV using the
key.
3. Connect the test leads.
4. After a short settle time, the reading will
be displayed automatically.
Measuring Other Parameters
The BMM500 Series can be used to measure
numerous quantities from temperature to
current to windspeed through the use of mV
output probes. Any compatible probe with a
known output ratio can be used. eg: a
temperature probe with output ratio of 1mV/ºC
will cause the display to indicate directly
in ºC Certain probes require zeroing, eg
windspeed anemometer. The mV zero option
described below provides this facility
Zeroing of d.c. mV (no a.c. mV zero facility)
To zero the d.c. mV range, short the leads
together in the d.c. mV position, wait for the
reading to settle and then press the TEST
button. Up to 9,9mV can be zeroed on the d.c.
∼
mV range. The symbol
indicate the zero has been adjusted.
