VERIFYING A PROPER SET-UP OF THE DM-II PRO
IMPORTANT NOTE:
Always perform this check. it will only take you a minute to verify a correct set-up, but you may
lose weeks or months of work if the DM-II PRO was set-up improperly.
Step 1 - Push the METER button. Check the following:
• P (Real Power) on each of the phases should be positive. If it is negative, reverse the
direction of the CT to make the color dot and Amprobe logo face the opposite way.
• Check if voltage and amperage (current) ranges on each of the phases are within expected
values. For example if nominal voltage of the system is 480V, but you are reading only
270V something is apparently wrong. In this case double -check the set-up of the test leads
and the DM-II itself.
The meter mode allows you to view real time readings of voltage, current, power, power factor.
Step 2 - Begin meter mode by pressing METER button. For definitions of terms see Pages 16 & 17.
Depending on phase set-up, there are different screens for you to view data.
