IMPORTANT!
All incoming power sources must be turned off during installation. Setup can be performed by qualified personnel only.
uring operation of the meter, hazardous voltages are present on the input terminals. Failure to observe precautions can result
in serious or even fatal injury, or damage to equipment.
Please refer to the installation and operation manual for further information.

Elementary Setup
All setups can be performed directly from the display panel or via communications using PAS
communication software, except for ommunications and Display setups, which must be performed
directly on the instrument panel.
To set the CT Primary current, perform the following steps:
• Press 3 times: CHG should blink.
• Press 2 times:
• Press ▲ 2 times:
• Press : "5" should blink.
• Use the ▲▼ arrows to scroll to the desired value
(press ▲▼ continuously for quick scrolling).
• Press to save the selected value.
• Press (X3) to return to the display menu.

Navigating in Display Mode
The front panel has a simple interface that allows you to display numerous measurement parameters in
up to 38 display pages. For easier reading, the parameters are divided into three groups, each
accessible by a designated key. These are:


 ommon measurements - no selection key


 Min/Max measurements - selected by the key


 Energy measurements - selected by the key
The up/down arrow keys are used as follows in isplay Mode:
Scrolls through the pages downward (forward)
Scrolls through the pages upward (backward)
Returns to the first page within current measurement group
For each display page, up to three parameters can be displayed. The Load bar graph displays the
percentage of the highest of 3 phases current measured by the PM130.
Selecting a Display Page
• Press the ▲▼ to scroll through display pages.
Selecting ommon Measurements
• Press the key pointed to by the illuminated round LE below the front panel display. If no LE is
lit up, the front panel is currently displaying the common measurements parameters.
Selecting Min/Max Measurements
• Press the key. Use the ▲▼ to scroll through Min/Max and Max. demand measurements.
Selecting Energy Measurements
• Press the key. Use the ▲▼ to scroll through the different energy readings.
