Basic Unit
A company needs to monitor the power supply
voltage and load current of a 12 VDC motor.
Voltage: A Mini-Max DC Volt meter, configured
for the 20 volt range, is installed in parallel with
the power source. The IN HI is connected to
the positive lead of the power supply. The IN
LO is connected to the negative lead of the
power supply.
Current: A second Mini-Max DC Volt meter,
configured for the 200 millivolt range, is used
with a 100A/50mV shunt (sold separately) to
measure the load current.
The meter is first scaled to read 100.00 at
50mV, by applying a 50mV input to the meter
and adjusting R9 and R12 until the display
reads 100.00. The meter is connected to the
shunt, and the shunt is installed in series on the
negative leg of the power supply. The positive

The WARNING sign denotes
a hazard. It calls attention to
a procedure, practice, or the
like, which, if not correctly
performed or adhered to,
could result in personal injury.
The CAUTION sign denotes a
hazard. It calls attention to an
operating procedure, prac-
tice, or the like, which, if not
correctly adhered to, could
result in damage to or
destruction of part or all of the
instrument.
