Cautions
ØBlock vehicle wheels from movement before releasing brakes.
ØThe antenna must be fully exposed for a clear radio signal.
ØDo not weld while the tester is connected to the trailer. The 930 tester
is grounded to the chassis and will be damaged.
ØDo not hook up electrical devices on the same trailer that the tester is
diagnosing. The tester needs a clean power supply.
ØDo not lengthen the existing power cord on the tester. Attach the
tester power cord directly to a 12-volt battery or a regulated power
supply. Lengthening the power cord will cause a power drop.
ØBe aware of voltage spikes. The tester will only operate on regulated
power. Use a 12-volt battery or LITE-CHECK 325S Regulated Power
Supply.
ØDo not charge a battery while using the tester, except mobile
installations using a vehicle alternator. Using a battery charger as a
power source will damage the tester.
ØThe tester will not operate efficiently
below 11.0 volts and will indicate “LOW
BATTERY VOLTAGE”.
ØThe tester may shut down if the voltage drops below 9.0 volts.
ØIf operating gasoline motors near the tester, be sure that they have
static suppression on the engine. Static can cause radio interference.
ØThe emergency air must be applied before the service brakes will
operate.
