The following parameter can be configured by simply entering as prompted by the software package.
· Input type (K,J,E,N,T,R,S,mV,PT100,mA)
· Low range
· High range
· Units (°C, °F, mV, mA)
· Burnout (direction of output current on sensor burnout)
· Output Range (0 to 10), (0 to 5), (0 to 1), (1 to 5), and (2 to 10) V
· User Trim (option to lock out front panel trim function)
Factory default:
Input type = P
Units = C
High Range = 100
Low Range = 0
Burnout = UPSCALE
Output range = (0 to 10) V
User Trim = ON
IMPORTANT The SEM1620 can be configured whilst connected and powered, but a portable battery powered computer must be used to avoid the effects of ground loops.

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 front panel, of the
conditioner, 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 Connect input simulator or sensor. Connect supply to a 24 V dc,
connecting a digital volt current meter to output. Turn supply on, set
input to either offset or span calibration point.

The conditioner will
automatically detect the correct
trim point (offset or span) based
on the output current drive.
Offset will be trimmed when the
output voltage is within ± 0.1 V
of offset output, span when the
output voltage is within (50 to
105) % of output range.
