6. MAINTENANCE & TROUBLESHOOTING
6.1 Replacing the Fuse
Prevent possible electrical shock and/or damage to the meter – disconnect power
to the meter PRIOR to wiring.
6.1.1 Flowmeter Fuse
The fuse located on the front panel of the flowmeter (upper right corner) protects the instrument from
overcurrent or short circuits from the internal battery. It is rated at 3 A, 250 V. The sheet metal access
cover does not need to be removed since it has a hole for accessing the fuse. To replace the fuse:
1. Disconnect power from the flowmeter, and determine the cause of the fuse failure; correct if known.
2. Open the door of the flowmeter, and use a small, flat-bladed screwdriver to remove the fuse and
replace it with another fuse of the same rating.
3. Reconnect power to the flowmeter and verify that the unit operates properly and the newly-installed
fuse does not blow.
6.1.2 Breakout Box Fuse
The fuse located in the breakout box protects the instrument from overcurrent from the battery charger/AC
adapter output. To replace the fuse:
1. Disconnect power from the flowmeter and disconnect the breakout box from the flowmeter and battery
charger/AC adapter.
2. Remove the 4 screws from the cover of the breakout box, and use a small, flat-bladed screwdriver, to
remove the fuse and replace it with another fuse of the same rating.
3. Reconnect power to the flowmeter and the breakout box to the battery charger/AC adapter, and verify
that the unit operates properly.
6.2 Charging the Printer Battery
Charging the printer battery is a simple procedure. Connect the printer to the printer power cable on the
breakout box (if battery charger/AC adapter is connected). Note the following cautions PRIOR to charging
the printer battery:
• If the battery is fully discharged, the battery charge time is 15 hours. DO NOT
charge for more than 24 hours.
• Do not connect the battery charger/AC adapter directly to the printer. The
voltage and polarity output of the charger do not match required input of the
printer. If they are directly connected, the printer battery can explode or the
printer can be seriously damaged.
