POINT
• The calibration parameters "C1" can be made to be read by setting "1" (extended
function parameter valid) in Pr. 30 "extended function display selection".
• Set the value of the calibration parameter C1 "AM terminal calibration".

REMARKS
• Depending on the set value, it may take some time for the needle to move.
• If "1" is set in Pr. 30 "extended function display selection", the calibration parameter C1 "AM
terminal calibration" can also be set in the external operation mode.
POINT
By setting the Pr. 54 "AM terminal function selection" value, preset Pr. 55
"frequency monitoring reference" or Pr. 56 "current monitoring reference" to the
running frequency or current value at which the output signal is 5V.
At 5V, the meter generally deflects to full-scale.
