To select a decimal point, connect the appropriate DP pin (DP1, DP2, or DP3) to the DP COMMON (HOLD).
DP inputs may remain unconnected (open).
Connect HOLD to DP COMMON (HOLD). If this feature is not required, the DP COMMON (HOLD) pin may remain
unconnected (open).
Connect the IN HI and IN LO to the signal to be monitored.
Connect power to the L1 and L2 terminals. For AC powered units, L1 and L2 are not polarized.
For 9-32 DC powered units, L1 must be positive with respect to L2.

Mini-Max indicators have limited-range coarse
and fine adjustments for display scaling.
There are no optional connections required
for these to function. The “COARSE” calibra-
tion R12 will allow a limited range of scaling
values. The meter can be scaled down to 1/2
the value of the input or scaled up to 2 times
the value of the input or a maximum reading
of 1.999, which ever is lower. Example: a 2
Amp input has a maximum reading of 1.999
counts, so you can’t double the 2 amps, but
you can make 1 AMP to read 1.9999.
“FINE” calibration R9 allows for an approxi-
mate range of 1% of the “coarse” calibration.
Apply full scale input to the meter. Adjust R12
to be within 1% of the desired scaled value,
then use R9 to obtain the final desired result.
