4. AmWatt™ Meter
AmWatt™ Hand-held Appliance Load Tester by
Reliance controls. This one-of-a-kind meter
gives instant accurate readout of amps or watts
used by common cord-connected household
appliances and lights. It is a useful consumer
tool for rightsizing a generator or determing the
load a device draws (under 15 amps or 1800
watts).
5. Multi-Meter & Analog Meter
Resistance tests should be done with a digital
meter. An analog ohm meter will not read a 10
or 20 percent variance from 1 ohm or less. Be
certain to "zero" an analog meter before use.
Also, use clips to connect the leads to the wires
being tested. holding both test wires to the leads
with your hands will distort the test results. An
analog meter is required to test condensers on
conventional generators.

3. Engine tachometer
Use of the PET-1000 or PET-2000DX engine
tachometer made by Oihama Kogyo Co., Ltd. is
recommended.
Note that the reading may not be right if the
position of the engine tachometer is wrong.
Keep it away from the engine.
