CHAPTER 3: STAND-ALONE ANALOG CALIBRATION AND SET UP
INTRODUCTION
This chapter contains the procedures to
perform an analog calibration and set up
system parameters for the STXplus.
TRIMMING THE CURRENT OUTPUT
Prior to calibration, check and adjust the
current output as necesary. If the
calibration of the device receiving the current
output does not match the calibration of the
current output, follow the appropriate
procedure below to trim the 0mA, 4mA,
and/or the 20mA current output(s).
If the STXplus is off, apply power and let it
warm up for at least 15 minutes before
proceeding.
NOTE
If you do not press a button within
15 seconds, the STXplus exits the
programming mode.
Trim the 0mA Current Output
1. Press the DOWN or UP buttons until the
PARAM LEDs look like:
Press the ENTER button.
2. Press the UP button to adjust the 0mA
up and press the DOWN button to adjust
the 0mA down. When satisfied, press the
ENTER button.
Trim the 4mA Current Output
1. Press the DOWN or UP buttons until the
PARAM LEDs look like:
Press the ENTER button.
2. Press the UP button to adjust the 4mA
up and press the DOWN button to adjust
the 4mA down. When satisfied, press the
ENTER button.
Trim the 20mA Current Output
1. Press the DOWN or UP buttons until the
PARAM LEDs look like:
Press the ENTER button.
2. Press the UP button to adjust the 20mA
