Display Scaling
Span Adjustment:
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” calibration 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 19999, which ever is lower.
Example: A 2 volt input has a maximum reading of
1.9999 counts, so you cant double the 2 volts, but
you can make 1 volt to read 1.9999. The “fine” cal-
ibration R9 allows for an approximate range of 1% of
the “coarse” calibration. Apply the 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.
Offset Adjustment:
To adjust the offset, apply the off-
set input signal. (e.g. 4 mA on 4-20 mA input). Use
R7 for a “coarse” adjustment of the offset. The offset
can be scaled up or down approximately 2500
counts. Adjust R7 to within 1% of the desired scaled
value, then use R6 to obtain the final desired result.

Decimal Point:
To select a decimal point, connect the appropriate DP pin (DP1, DP2, DP3, or DP4) to DP COMMON (HOLD). Unused DP inputs
may remain unconnected (open).
Reading Hold:
Connect DP4/HOLD to DP/COMMON (HOLD). If this feature is not required, the HOLD pin may remain unconnected (open).
Hold is optional on this model, and when so equipped, replaces DP4. This feature is available from our modification centers.
Input Signal:
Connect the IN HI and IN LO to the signal to be monitored.
Supply Power:
Connect the power to the L1 and L2 terminals. For AC powered units, L1 and L2 are not polarized.
For 9-32 VDC powered units, L1 must be positive with respect to L2.
