To select a decimal point, connect the appropriate DP pin (DP1, DP2, DP3 or DP4) to the DP COMMON (HOLD). Unused 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 uncon
tion centers.
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.

DP4/
Mini-Max indicators have limted 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, but not scaled
up. Maximum scaling is maximum input or
a maximum reading of 1.9999, which ever is
lower. The “FINE” calibration R9 allows for
an approximate 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.
