IMPORTANT :
Before using the
Portable Flow Tester
for the first time,
the battery must be charged for at least six (6) hours.
The
Portable Flow Tester
is powered by a rechargeable battery and must be
charged regularly. A fully charged battery will provide approximately six hours of
operating time. When the tester is not in use, the ON/OFF switch should be left in the
OFF position. The LOW BATTERY WHEN LIT
indicator will illuminate when the
battery needs to be charged.
Charging
A 120 volt charger is mounted inside the box. A 120 VAC power cable is supplied
to power the charger. To charge the internal battery plug the cable into the AC
CHARGER input on the front panel and connect the other end to a standard 120 VAC
electrical outlet.
The battery must be charged with the ON/OFF switch in the OFF position.
Replacing the Battery
The battery used in the tester is a 12 VDC, 3.4 Ah, maintenance free, sealed lead
acid battery. The battery should last 3 to 4 years depending on use.
To remove the battery:
1. Remove the four retaining screws on the bottom of the flow tester case.
2. Open the cover and lift out the front panel.
3. Remove the two screws holding the battery to the front panel.
4. Remove the wires form the battery terminals.
To install a battery do the steps in reverse.
Alternate Power Sources
If any problems occur with any of the charging circuits, or if it is found during a
test that the battery is not charged, it is possible to power the tester directly from either
a 120 VAC or a 12 VDC source.
The tester will operate normally and can be used to perform flow tests when
connected to a 120 VAC power source. Plug the AC Power Cable into the AC
CHARGER input on the front panel and connect the other end to a standard 120 VAC
electrical outlet. The flow tester will work from the internal DC power supply.
A 12 VDC power source (car or truck battery) can also be used to power the flow
tester. Plug the optional 12 VDC Power Cable into the EXTERNAL POWER DC
VOLTAGE input on the front panel and connect the other end to a 12 VDC source.
