High Strength Panel
Mounting Kit
P/N: OP-PMA96X48
For extra strength in portable applications, the 8 DIN
spacers should be snipped off and the Mosaic fitting
cutout used. Alternatively, the High Strength Panel
Mounting Kit (Part # OP-PMA96X48) can be used.
Panel adaptor plates are
available to retrofit most
existing panel cutouts.
Input Module Calibration Procedures Continued
Span to produce the required digital reading.
Example B
: 1 to 5 V to read –100 to 1500 °C.
Signal Span = 4V, Digital Display Span = 1600 counts
1 If the module has an INPUT RANGE Header the 2 V position
should be selected. This will provide a digital display of 1600 counts
for an input of 1.6 V which is (1.6 ÷ 4) = 40% of the examples 4 V
signal span. To scale down the Signal Span to 40% select the 40%
Signal Span position on the SPAN ADJUST Header (position 2).
2 If the module is a Process Input 1-5 V DC type, select the (Hi
Range) position on the SPAN RANGE Header and the 100% Signal
Span position on the SPAN ADJUST Header (position 5, max
increase). This will provide a digital display of 1600 counts for an
input of 4V which is 100% of the examples 4V Signal Span.
3 Set the ZERO OFFSET RANGE Header to the center position (no
offset). Apply 1 V and adjust the SPAN pot until the display reads
400 . A 4V input would then read 1600 counts.
4 Set the ZERO OFFSET RANGE Header to the negative offset
position. If the module has a ZERO ADJUST Header select the
position that will provide a negative offset of ≈ –500 counts.
Apply 1 V and adjust the ZERO pot until the display reads –100.
Apply 5 V and check that the display reads 1500.
Example C
: 4 to 20 mA to read 00.0 to +100.0%
Signal Span = 16 mA, Digital Display Span = 1000 counts.
1 The full scale Signal Span of the Process Input 4-20 mA modules is
0 to 20 mA for a full scale Digital Display Span of 0 to 2000 counts.
This will provide a digital display of 1000 counts with an input of only
10 mA which is (10÷16)=62.5% of the examples 16 mA signal span.
2 To scale down the Signal Span to 62.5% select the (Hi Range)
Position on the Span Range Header and the 70% Signal Span
position on the SPAN ADJUST Header (position 2).
3 Set the ZERO OFFSET RANGE Header to the center position (no
offset). Apply 4 mA and adjust the SPAN pot until the display reads
250 . A 16 mA input would then read 1000 counts.
4 Set the ZERO OFFSET RANGE Header to the positive offset
position. If the module has a ZERO ADJUST Header select the
position that will provide a negative offset of ≈ –250 counts. Apply
4 mA and adjust the ZERO pot until the display reads 000. Apply
20 mA and check that the display reads 1000. Select decimal point
1XX•X to display 00.0 to 100.0.
1999 (counts) to 001 (one count).
If the module has an INPUT RANGE Header, and the required full
scale Digital Display Span (counts) is to be larger than the directly
measured value of the input Signal Span, then the next lower range
on the INPUT RANGE Header should be selected. The resulting over
range Signal Span is then scaled down, by selecting the position of
the SPAN RANGE Header and or the SPAN ADJUST Header, which
will reduce the input Signal Span to a percentage, that the required
Digital Display Span can be reached by calibration with the SPAN pot.
Example A
: 0 to 10 V to read 0 to 1800 gallons.
Signal Span = 10V, Digital Display Span = 1800 counts
1 Select the 2 V INPUT RANGE Header position. This will provide a
digital display of 1800 counts with an input of only 1.8 V which is
(1.8÷10)=18% of the examples 10 V Signal Span.
2 To scale down the Signal Span to 18% select the 20% Signal Span
position on the SPAN ADJUST Header (position 1) or if the
module has a SPAN RANGE Header, select (LO Range) and
20% Signal Span position on the SPAN ADJUST Header
(position 2).
3 Apply a zero input or short the input pins. The display will auto zero,
or if the module has a ZERO pot, it should be adjusted until the
display reads zero.
4 Apply 10 V and adjust the SPAN pot until the display reads 1800.
Large offset scaling and calibration of process signal
inputs with modules that utilize ZERO ADJUST Headers
and or ZERO OFFSET RANGE Headers.
Texmate’s unique ZERO OFFSET RANGE Header enables the
use of a simple two step scaling and calibration procedure for those
process signals that require large offsets. This eliminates the back
and forth interaction, between zero and span settings, that is often
required to calibrate less finely engineered products.
The first step is to set the ZERO OFFSET RANGE Header to the
center position (No Offset) and scale down the Input Signal Span to
a percentage that will enable calibration with the SPAN pot to reach
the required Digital Display Span.
The second step is to set the ZERO ADJUST and or ZERO OFFSET
RANGE Header to provide a positive or negative offset of sufficient
counts that calibration with the ZERO pot will offset the Digital Display
