Table 22 ACAL Command
Syntax Description
acal<cr>
Use the acal command to calibrate the analog
current loop outputs.
After you give this command, the CH1 analog
output of the transmitter is set to the low limit
(4mA). Measure the output and enter the
measured value. After entering the low limit, you
must measure and enter the high limit (20mA)
also. The same procedure is then repeated with
CH2. Calculated coecients are printed after the
measured values are given.
