Grounding
For the PowerMaster
®
to properly stabilize and achieve the highest possible accuracy, the
MTA15Z must be properly grounded. Using the greed safety ground lead, insert the cable into
the green “VOLTAGE DRIVE” (BOTTOM) female receptacle. If using an alligator clip, connect to
a known earth ground. When using in a laboratory application, Powermetrix recommends the AC
Plug to Safety Banana Plug Adapter (part# 10-340-0045). This accessory allows the Auxiliary
power, Auxiliary neutral, and ground to be easily terminated for a standard US three-prong AC
wall outlet.
Voltage Lead Connections
1. Connect the Voltage Lead Set + Safety Aux Power cable to the PowerMaster
®
.
2. Remove all alligator clips from the ends.
3. Separate the “MEASURE” and “RETURN” from the stackable banana jacks.
4. Insert the cables labeled “MEASURE” into the “VOLTAGE MEASURE” receptacles
according to their color code.
5. Insert the cables labeled “DRIVE” into the “VOLTAGE DRIVE” receptacles according to
their color code.
6. Insert the green lead with alligator clip into the “VOLTAGE DRIVE” receptacle. Connect
the alligator clip to a known earth ground.
