User adjust function allows manual adjustment of the output current,
this is useful for minor calibration adjustment or trimming out any
sensor error, ± 5% of range adjustment is available at both offset and
span. Raise and lower buttons are provided on the front panel of the
transmitter, accessed using a 3 mm flat blade screw driver. Insert the
screw driver into the appropriate slot to operate the button. The
button has a click action.

1.0 Connect transmitter to a suitable Resistor decade box or
sensor. Connect output to a dc supply, connecting a digital mA
current meter in series with the output. Turn supply on, set
input to either offset or span calibration point.

The transmitter will
automatically detect the
correct adjust point (offset
or span) based on the
output current drive. Offset
will be adjusted when the
current is between (3.8 to
6) mA, span when the
current is between (18 to
22) mA. No trim action
occurs at any other current.

Power supply (10 to 30) Vdc
Resistor Decade box
User range function allows manual adjustment of the 4 mA and 20 mA
output range in relation to the input value.
Method
1.0 Connect the resistor decade box or the input sensor
using the three connection terminals. Connect the
to a (10 to 30) V C power supply, a digital ammeter
connected in series will be useful to
monitor the (4 to 20) mA current but is not essential.
Turn on the supply and allow 1 minute warm up period.
2.0 Set the resistance decade box to the equivalent resistance
of the sensor for the required low range temperature, or apply
required low range temperature to the sensor.
Allow 10 seconds to settle.
3.0 Press and hold the Low range A JUST button, marked with
a blue down arrow, until the STATE LE starts to flash, then
release the button.
Press and release the Low range A JUST button again, the
STATE LE will flash quickly for a short time and the new low
range will be stored. The output current will go to 4.0 mA.
4.0 Set the resistance decade box to the equivalent resistance
of the sensor for the required high range temperature, or apply
required high range temperature to the sensor.
Allow 10 seconds to settle.
5.0 Press and hold the High range A JUST button, marked with
a Red up arrow, until the STATE LE starts to flash, then
release the button.
Press and release the High range A JUST button again, the
STATE LE will flash quickly for a short time and the new high
range will be stored. The output current will go to 20.0 mA.
The ranging is now complete.
Note:- The Low and High user adjust can be set individually and
in any order as required.
