Operation and Programming Manual

mA Out Offset
Used to bias the analog output signal to a preset level. Any value from 0.00to 20.00 mA’s is valid. The
most common is 4.00mA’s.
Use higher offset values in PID mode, particularly if the cracking pressure of the regulator is higher than
normal.
USED IN: PID and Monitor mode
RELATED VARIABLES: mA shifter, mA gain
HEX ADDRESS: 0091 HEX ‐‐‐‐> SAME ADDRESS AS IN EMO‐2000
BYTES: 2 Bytes DEFAULT: 819 (4.00mA)
ASC form COMMAND: reading = 111; writing = 511; E returns the mA’s value; N returns
counts.
mA Gain factor
Used to scale the analog output to the expected input frequency. This scaling factor only applies in
monitor mode and does not affect PID. Since the top frequencies are anywhere from 3 Hz to 2000Hz,
there has to be a scaling possibility. Apply this formula to scale the gain factor correctly:
GAIN = mA’s x 8350/freq
where
 mA’s represents the requested mA’ output at the frequency
 freq is the top frequency expected at 20mA’s
The default value 167 causes the input frequency of 1000 Hz to generate a 20.00 mA output.
USED IN: Monitor mode
RELATED VARIABLES: mA shifter, mA gain, mA pointer
HEX ADDRESS: 0091 HEX ‐‐‐‐> SAME ADDRESS AS IN EMO‐2000
BYTES: 2 Bytes DEFAULT: 167
ASC form COMMAND: reading = 116; writing = 516; E and N return an integer number.
