to the following maximums:
“99999.999”
if TD = 3
“999999.99”
if TD = 2
“9999999.9”
if TD = 1
“ 99999999”

“99999.999”
if RD = 3
“999999.99”
if RD = 2
“9999999.9”
if RD = 1

Set Total
See ST command above.
CN
Adjust 4mA output point
“CN=#(DATA)”
(DATA)
is the integer value that the HIT-2A sends to the
4-20mA converter to output 4mA
This parameter is passed to the HIT-2A to adjust the 4mA
output point of the device. This value is used in production
at the test step to calibrate the 4mA output point.
“CN”
will cause an Invalid Command response and absence of the
# symbol will cause the HIT-2A to ignore the data.
CM
Adjust 20mA output point
“CM=#(DATA)”
(DATA)
is the integer value that the HIT-2A sends to the
4-20mA converter to output 20mA
This parameter is passed to the HIT-2A to adjust the 20mA
output point of the device. This value is used in production
at the test step to calibrate the 20mA output point.
“CM”
will cause an Invalid Command response and absence of the
# symbol will cause the HIT-2A to ignore the data.
