4. OPERATION
4.1 BATTERY INSTALLATION AND BATTERY
STATUS
Never replace batteries with flexible measuring head
installed on conductor to be tested or output connected to a
measuring device.
Never operate the unit without the battery cover fitted.
The METRAFLEX require two AA MN1500 LR6 alkaline batteries
for operation. The battery compartment is accessed from the rear
of the electronics enclosure.
Battery status is indicated by an orange LED on the front of the
integrator module. This LED will flash one time when the unit is
switched ON. The length of time the LED is lit will increase as
battery life decreases. Continuous lighting of LED indicates low
battery and requires batteries to be replaced.
Should you suspect a depleted battery or the low battery LED
blinking, proceed as follows.
1. Turn “OFF” all power to the unit and measurement circuits.
2. Set the probe selector switch to the “OFF” position.
3. Remove the flexible current probe from around the conductor
of your measurement circuit. Disconnect the output from the
measuring unit. Remove the external power supply cable.
4. Rotate the battery lock screw (1/4 turn) until it aligns with the
unlock symbol. The battery cover can now be removed.
5. Install the replacement batteries into the battery holder.
Observe correct polarity.
6. Replace the battery cover and turn the battery lock until it
aligns with the lock symbol.
