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.
METHOD
1.0 In USBSPeedLink software set the “Buttons” drop box to
trim (this is the default setting).
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.

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 In USBSPeedLink software set the “Buttons” drop box
to active range (this is not the default setting).
1.0 Connect the resistor decade box or the input sensor to the
SEM1605P using the three connection terminals. Connect the
SEM1605P to a (10 to 30) VDC power supply, a digital ammeter
connected in series with the SEM1605P 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 for the SEM1605P to settle.
3.0 Press and hold the Low range ADJUST button, marked with
a blue down arrow, until the STATE LED starts to flash, then
release the button.
Press and release the Low range ADJUST button again, the
STATE LED 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 req uired high range temperature, or apply
required high range temperature to the sensor.
Allow 10 seconds for the SEM1605P to settle.
5.0 Press and hold the High range ADJUST button, marked with
a Red up arrow, until the STATE LED starts to flash, then
release the button.
Press and release the High range ADJUST button again, the
STATE LED 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 of the SEM1605P is now complete.
Note:- The Low and High u ser adjust can be set individually and
in any order as required.
