OUTPUT ADJUSTMENTS:
The unit has two potentiometers for adjustment. The upper
potentiometer controls the 20mA setpoint and the lower
potentiometer controls the 4mA setpoint (see Figure 2). The
4mA output range can be adjusted from 3mA to 5mA. The
20mA output range can be trimmed from 50% to 100% of
the selected range. To adjust the output, initially turn the
20ma adjust 20 turns CW for starting position. Input 0
frequency and adjust the 4 mA pot. Connect your maximum
frequency and adjust the 20 mA pot.
