General Information
Product Introduction
The MTA15Z is a self-contained accessory to the PowerMaster
®
analyzer. This accessory
accommodates testing of any ANSI socket-based meter using a load provided by the
PowerMaster
®
. The MTA15Z includes a zero-insertion force (ZIF) socket that is automatically
configured by the PowerMaster
®
and requires no jumpers for testing. For mechanical meters, the
user can pull the supplied pins for the lid, rotate the case upright, and test appropriately.
Currents are injected via the PowerMaster
®
by the 6mm terminated lead set. Voltages are
injected using the standard voltage lead set, and are fused for each phase on the MTA15Z.
Once the service type is selected in the PowerMaster
®
, the user will select a Phantom Load
Setup to provide the test. Results are saved as normal in the PowerMaster
®
and will be
downloaded using the Meter Site Manager 2 software.

Safety
Operation of the PowerMaster
®
and the supplied accessories and adapters can present the user
to potentially hazardous conditions. Please follow all required safety procedures set forth by the
user’s safety organization within the company. If no safety organization exists, please follow all
applicable OSHA rules and standards for PPE (Person Protective Equipment) when working in
high voltage and low voltage environments. This equipment should be used by trained and
qualified personnel ONLY.

Rev: 1.1 Page 5 of 13
Tips for Testing:
1. Connect the green safety ground to a true earth ground before testing begins. Remove
the green safety ground last after testing is complete.
2. Never disconnect the CURRENT or VOLTAGE leads from the PowerMaster
®
while driving
a load into the MTA15Z.
3. Pressing the “ON” key on the PowerMaster
®
while driving a load can be used as an
emergency shutoff. The auxiliary power switch on the front panel of the PowerMaster
®
will provide the same function as well.

1 Setting Up
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 Ground + 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.
7. Connect the AUX PWR and AUX NEU to a voltage source between 100-530VAC.
Voltage cables from PowerMaster

Auxiliary power connected to voltage source
(100-530VAC)
WARNING: Input voltage must be supplied from the Model 7332 or 7335 only. Any other source
voltage from the service or another device will cause damage to the MTA15Z that is
not covered under the 1-year warranty.

Current Lead Connections
1. Connect the 3-Phase Current Direct Probes (terminated with 6mm plugs) to the
PowerMaster
®
.
2. Insert the probes into the “TEST CURRENT IN”. According to the color code, plug the
phase DRIVE into the blackfemale receptacle (DRIVE, BLACK) and the RTN into the
white female receptacle (RETURN, WHITE) for each phase.
