Scaling Analog Outputs for 0-2 mA and ±2 mA
The 0-1mA and ±1mA current outputs provide a 100% overload, and actually output currents up to 2 mA
and ±2mA whenever the output value exceeds the engineering scale you set for the 1 mA or ±1mA.
The output scales for 0-1 mA and ±1 mA analog outputs are programmed for 0 mA and +1 mA regardless
of the required output current range.
To use the entire output range of 2 mA or ±2 mA, set the analog output scales as follows:
• 0-2 mA: set the 1 mA scale to ½ of the required full scale output for uni-directional parameters,
and set the 0 mA scale to the negative full scale and the 1 mA scale to zero for bi-directional
parameters.
• ±2 mA: set the 1 mA scale to ½ of the required full-scale output for both uni-directional and bi-
directional parameters.
For example, to provide the 0 to 2 mA output current range for Volts measured by the meter in the range
of 0 to 120V, set the 1 mA scale to 60V; then the 120V reading will be scaled to 2 mA.
5.2.6 Configuring Counters
The PM130 PLUS has four six-digit general counters that can count pulses delivered through the device
digital inputs with a programmable scale factor. Each counter can also be incremented in response to any
internal or external event, checked and cleared through the Control Setpoints.
Using the Front Display
Select Cnt from the main menu. This menu entry appears only if the optional digital I/O module is plugged
into the meter.
Use the UP and DOWN arrow buttons to scroll to the required counter.
To select a counter parameter:
1. Press the SELECT button to activate the middle window.
2. Use the UP and DOWN arrow buttons to scroll to the required parameter.
To change the parameter value:
1. Press the SELECT button to activate the lower window.
2. Use the UP and DOWN arrow buttons to select the required value.
3. Press ENTER to confirm the new parameter setting or press ESC to discard changes.
4. You are returned to the middle window and can configure another parameter.
To store your new settings:
1. When the middle window is highlighted, press the ENTER button.
2. You are returned to the upper window and can select another counter or exit the menu.
3. Press ESC to exit the menu.
See Table 25 for the counter options.
