Meter power supply
5.1 Monitoring of the power supply voltage
The charge level of the batteries or rechargeable batteries is indicated by the symbol in the right
upper corner of the display on a current basis:
Batteries charged
Batteries discharged
Replace or recharge the batteries!
Note:
The
symbol in the display means that the supply voltage is too low and indicates that the
batteries must be replaced or recharged,
Measurements performed with an insufficient supply voltage feature additional errors which the
user is unable to evaluate.
5.2 Replacing batteries (rechargeable batteries)
MRP-201 is powered by four R6 disposable or rechargeable batteries (alkaline batteries are
recommended). The (rechargeable) batteries are placed in the compartment at the bottom of the
enclosure.
WARNING:
Before replacing the batteries, disconnect the test leads from the meter.
To replace the batteries:
1. Disconnect the leads from the measuring circuit and turn off the meter,
2. Remove the screw that secures the battery cover (the bottom of the enclosure),
3. Replace all batteries. Observe the correct polarity when putting new batteries ("-" on the elastic
part of the contact plate). Reverse polarity will not damage the meter or the batteries, but the
meter will not work.
4. Place and tighten the battery compartment cover.
After replacing batteries/rechargeable batteries and turning
on the meter, it starts in the power supply source selection
mode.
