Basic Unit
Your Mini-Max Voltage Indicator can be configured by making an entry for each box
A company needs to monitor the power
supply voltage and load current of a
12VDC motor.
Voltage: A Mini-Max DC Volt meter, con-
figured 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 cur-
rent.
100.0 at 50mV, by applying a 50mV input
to the meter and adjusting R9 and R12
until the display reads 100.0. The meter is
connected to the shunt, and the shunt is
installed in series on the negative leg of the
power supply. The positive lead of the
shunt is connected to the IN HI terminal,
and the negative lead connected to the IN
Note: Models for DC voltage, process, AC TRMS voltage and current, AC frequency and tempera-
ture are also available.

External shunts enable digital panel meters to
indicate higher currents than can be provided
with self-contained internal shunt meters. The
shunt is installed in series with the load and
source.
which is sent to the display unit. The Mini-Max
can be scaled to display the actual current
between the load and the source. Simpson
offers both portable and switchboard shunts.
Each portable shunt includes 5’ leads.

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