Note that in the Manual Mode, the present pH value is displayed in the top line and the Control Adjustment is
made in the second line.
Each of the PID controller options used to configure and tune the loop is shown below for a sensor type of
contacting or electrodeless conductivity.
PID Function Edit Range Default Setting
Set Algorithm ISA or Velocity ISA
Set Full-Scale 0 to 5000 S/cm 2000 S/cm (Do not change)
Set Zero-Scale 0 to 5000 S/cm 0 S/cm (Do not change)
Set Setpoint 0 to 5000 S/cm 1000 S/cm
Set Proportional Gain –99.99 to +99.99 0.00 (+ is direct action, – is reverse action)
Set Integral Gain 0.00 to 50.00 reps/min 0.00 reps/min
Set Derivative Gain 0.00 to 10.00 seconds 0.00 seconds

0 to 9999 seconds 0 seconds
Set Manual Reset 0.0% to 100% 0.0%
Manual Mode Control: 0.0% to 100% 0.0% (Process value is displayed)
When the configuration and tuning settings are made, select PID as the Parameter for current loop 1 or current
loop 2.
Integral gain can be disabled by entering “0.00” to provide only PD controller action.
To quickly get to the PID controller set point for fine tuning, press the ENTER and RIGHT ARROW KEYS at the
same time from a measure screen. This feature is present only when the personality module installed in the
AV88 is pH, contacting conductivity or toroidal conductivity.
