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, configured
for the 20 volt range, is installed in parallel with
the power source.
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 100.0 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 nega-
tive leg of the power supply.
The positive lead of the shunt is connected to
the IN HI terminal, and the negative lead con-
nected to the IN LO terminal.
The Mini-Max units will indicate the power
supply voltage and load current of the motor.
Note: Models for DC current, process, AC TRMS voltage and current, AC frequency and tempera-
ture are also available.
Note: Special scaling is available from the factory at the time of ordering.

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. The shunts produce a DCmV
drop 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 WARNING sign denotes
a hazard. It calls attention
to a procedure, practice, or
the like, which, if not cor-
rectly performed or adhered
to, could result in personal
injury.
The CAUTION sign denotes
a hazard. It calls attention
