amprobE INStruCtIoNS
The Amprobe is a multi-range, combination ammeter
and voltmeter.
Voltmeter Scales: 150 VOLTS 600 VOLTS
ammeter Scales: 5 AMPS 40 AMPS
15 AMPS 100 AMPS
1. When used as an ammeter, the tongs are placed
around the wire being measured with the rotary
scale on the 100 amp range. Then rotate the scale
back to the smaller ranges until an exact reading is
indicated.
2. When used as a voltmeter, the two leads are
clipped into the bottom of the instrument with the
rotary scale on the 600 volt range. If the reading is
less than 150 volts, rotate the scale to the 150 volt
range to get a more exact reading.
ohmmEtEr INStruCtIoNS
The Ohmmeter is used for measuring the electrical
resistance of a wire circuit. The unit of measurement is
called an Ohm.
1. The knob at the bottom of the Ohmmeter is
adjustable through six ranges:
rX
1
= R x 1
rX
10
= R x 10
rX
100
= R x 100
rX
1000
= R x 1,000
rX
10k
= R x 10,000
rX
100k
= R x 100,000
2. The round center knob is for the purpose of
adjusting the instrument to zero (0) after clipping
the two ohmmeter leads together. this must be
done every time the range selection is changed.
use ohmmeter only with powEr
off.
If your ohmmeter
is digital readout
type, refer to the
instructions that
came with it.
