USER TRIM
Power Supply (24VDC)
Input Simulator
User trim 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 back, 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 Ensure the SEM710 is correctly configured. Connect transmitter to
a suitable input simulator or sensor. Connect output to a 24V dc
supply. Turn supply on, set input to either offset or span calibration
point.
2.0 During normal operation the SEM710 Display reading is calculated
from the output current drive not directly from the input, therefore the
display may be used to monitor trim adjustment. If required the output
current may also be monitored with a current meter.
3.0 If the input falls outside the ranged output the SEM710 will enter
burnout condition on the output, but will continue to display the
temperature. The SEM710 will indicate this by alternating the display
to show 'OuER' or 'uND' depending on the burnout direction of the
input reading.
4.0 Trim output current by pressing either the raise or lower button,
single click to step advance , or press continuously to auto advance.
The SEM710 unit will automatically detect the correct trim point.

SEM710
The transmitter will auto-
matically detect the correct
trim point (offset or span)
based on the output current
drive. Offset will be trimmed
when the current is be-
tween (3.8 to 6) mA, span
when the current is between
(18 to 22) mA. No trim
action occurs at any other
current.

Trimming The Output Of An SEM710 Indicating Temperature Transmitter
A –In order to setup the SEM710 connect a USB
port on your computer to the USB port on the
SEM710 using a USB type-A / Mini USB 4-pin
cable. Start the Status Instruments USB LINK
Software and setup the temperature range that
you want the 4 to 20mA output to be. Also
make sure the TRIM feature is turned on.
Back of SEM710 Indicating Transmitter
B -In order to TRIM the output of an SEM710 Indicating Temperature Transmitter you must use a
temperature sensor simulator and do the following:
1. Connect your temperature sensor output from your temperature sensor simulator to terminals
1, 2, & 3 as soon below for a thermocouple or an RTD:
Thermocouple:
Connect positive lead to terminal 1.
Connect negative lead to terminal 2.
RTD:
Connect two same color leads to terminals 1 & 2.
Connect odd colored lead to terminal 3.
2. Connect the power leads from your temperature sensor simulator to the “+” and “—“ terminals
shown on the above drawing.
3. Enter the “TRIM” mode of the SEM710 Transmitter by holding down the “RAISE” button for
more than 2 seconds (when in the trim mode the “C” or “F” LED on the front of the unit will
flash).
4. Now set the temperature equivalent of the 4mA output on the transmitter and read the output
current on your sensor simulator. If it is above 4mA press the “LOWER” button until it is at 4mA,
if it is below 4mA press the “RAISE” button until it is at 4mA (you can also read the low
temperature of the output range on the transmitter indicator on the front of the transmitter).
5. Next set the temperature equivalent of the 20mA output on the transmitter and read the output
current on your sensor simulator. If it is above 20mA press the “LOWER” button until it is at
20mA, if it is below 20mA press the “RAISE” button until it is at 20mA (you can also read the high
temperature of the output range on the transmitter indicator on the front of the transmitter).
6. Once the TRIM is complete allow 30 seconds with no button presses for the transmitter to store
the settings and return to normal operation.
