Procedure:
1. Verify all connections according to the hookup instructions and wiring diagram.
2. Using the external power supply, select the desired voltage, current, and power factor for
the test. This will be a series-parallel load.
3. At the Calibration Check screen, select the correct energy test mode (Whr, VARhr, or
VAhr) and enter the desired time and Kh value of the standard. When using a series
parallel load, the Kh value should be multiplied by 3 (ex. 0.00001 * 3 = 0.00003)
4. Press F6 (Start Test) to begin the test.
5. View and record results.
6. Press PREV to return to the Calibration Verification menu.

unit
2. PowerMaster
®
Calibration Cables Kit
3. PowerMaster
®
External Digital Cable (separate accessory)
4. External power supply (current and voltage source)
5. W-hr/Var-hr standard
6. AC adapter with a “pigtail” termination (line & neutral bare wires)
7. 18+ AWG wire for voltage and 12+ AWG wire for current
Hookup Instructions:
1. From the PowerMaster
®
, connect the one end of the Voltage calibration cable to line (red)
and neutral (black) of the W-hr/Var-hr standard.
2. From the PowerMaster
®
, connect the other end of the Voltage calibration cable to the
external power supply (red = V out HI, white = V out LO, yellow = V sense HI, blue = V
sense LO). Connect the ground (green) to a known earth ground.
3. From the PowerMaster
®
, connect the Current calibration cable for line (red) to the W-
hr/Var-hr standard’s current return. Then, connect the neutral (black) to the external
power supply’s current output neutral (LO).
4. From the external power supply, connect the current output (HI) to the W-hr/Var-hr
standard’s current.
5. From the PowerMaster
®
DIGITAL input, connect the External Digital Cable (STD IN) to the
pulse output on the W-hr/Var-hr standard.
6. From the W-hr/Var-hr standard, use the AC adapter to connect the auxiliary power from
the standard.
Procedure:
1. Verify all connections according to the hookup instructions and wiring diagram.
2. Using the external power supply, select the desired voltage, current, and power factor for
the test. This will be a series-parallel load.
