CALIBRATION
NOTE: This is only a single point calibration. All trans-
mitters are factory calibrated to meet/exceed
published specifications. Field adjustment
should not be necessary.
The dipswitch allows the user to calibrate the sensor
through the software. Setting switch 4 ON will put the
transmitter into setup mode allowing the increment and
decrement to work. Once in setup mode, the output will
change to 50% (2.5V for 0-5V, 5V for 0-10V, 12mA for 4-
20mA). Each increment or decrement step will cause the
output to change by 0.1V for 0-5V, 0.2V for 0-10V, and
0.32mA for 4-20mA in setup mode. This can be used to
show the user how far offset the transmitter is. To see the
starting point again set switch 1 ON. This will show the
50% output again. When the unit is out of setup mode the
output will go back to RH output.
Increment RH Output
This will shift the RH output linearly up in 0.5% steps.
Switch 4 must be set to ON first. After switch 4 is on, each
time switch 5 is set ON the RH output will increase by
0.5%. The increase goes into effect each time switch 5 is
set to ON.
Decrement RH Output
This will shift the RH output linearly down in 0.5% steps.
Switch 4 must be set to ON first. After switch 4 is on, each
time switch 6 is set ON the RH output will decrease by
0.5%. The decrease goes into effect each time switch 6 is
set to ON.
Reset RH Output
This will reset the RH output back to the original
calibration. Switch 4 must be set to ON first. After switch 4
is on, toggle switches 5 and 6 ON then OFF. After 5 and 6
are OFF slide switch 4 OFF.
When all calibration is completed, remember to place the
switches back into the positions that correspond to the
output needed as shown in Figure 3.
