Triplett Model 9310-A
2.30
Do not modify the meter. Changing the design may make the meter unsafe
and may result in injury to the user.
2.31
Use caution when attempting to evaluate if a dangerous voltage is present.
The meter will not read AC voltage if it is set to DC, nor will it read DC if it
is set to AC. For example, if the meter is set to 400VDC, it will not measure
a dangerous AC voltage, even if the probes are inserted into a household
AC wall outlet.
2.32
Do not touch the metallic portion of one test lead if the other test lead is
connected to a live circuit. The current from the live circuit may pass
through the meter and appear on the unconnected test lead. Failure to
observe this warning may result in user injury.
2.33
Do not attempt to use meter when no display is present on LCD. Doing so
may damage the meter and/or injure the user.
2.34
Use caution when measuring circuits containing capacitors. Capacitors can
store dangerous or lethal levels of electricity, even when the circuitry which
they are in has been disconnected from its power source. Some capacitors
could source enough energy to damage the meter and/or injure the user.
2.35
Use caution when using this meter to measure voltages in industrial appli-
cations where the High Energy circuitry is used. High Energy circuitry is
usually regarded as any circuitry capable of supplying over 4000 watts to a
load before a safety device (like a fuse) interrupts the circuit. For maximum
safety, use of Lineman’s Gloves conforming to ASTM D120 is recommended.
See product specifications for Category III statement.
2.36
Do not attempt to test charged capacitors. Only discharged capacitors may
be tested. If you wish to test a capacitor, discharge it using an approved
method before connecting it to the meter.
Caution:
Some capacitors
can store dangerous lethal charges. Discharging these capacitors can be
dangerous unless an approved method is used. Failure to observe this pre-
caution may result in damage to the meter or injury to the user.
2.37
When you use the meter to check a high-voltage circuit, do not try to
connect both test leads at once. Instead, clip one probe to the neutral
or ground lead of the circuit (usually a bare, green, or white wire in AC
wiring circuits) using the insulated slip-on Alligator Clips. Then probe
for voltages with the other test lead. This helps prevent you from
accidentally touching a hot wire, since you need to concentrate on only
one test lead. Failure to observe this precaution may result in damage to
the meter or injury to the user.
