Page 2: General Description
General Description The POWER SERIES Plus digital switchboard meters incorporate the latest DSP microprocessor technology. Careful and thoughtful design has resulted in a family of user- friendly, field-adjustable meters. When ordering the 2493 meter, the following options are available: • AC Measuring Function(s): Volts, Amps, Watts, VARs, Power Factor, and/or Frequency. - Page 3 Volt / Amp / Hertz Specifications PRODUCT FUNCTION: AC Volts, 1 Phase or 3 Phases, 3 Wires or 4 Wires AC Amps, 1 Phase or 3 Phases Frequency ±0.2% of Reading ±0.1% of Full Scale ACCURACY: DISPLAY UPDATE RATE: 250 milliseconds OPERATING TEMPERATURE RANGE: -20 to +60 °Celsius -40 to +85 °Celsius STORAGE TEMPERATURE RANGE:...

Page 4: Configuring The 2493 Power Series
Plus CONFIGURING THE 2493 POWER SERIES METER Plus The new triple-display POWER SERIES can be configured for voltage and current inputs from instrument transformers, as well as analog outputs, Modbus or ASCII protocol Communications parameters and a rolling average display. All set-up functions can be performed using the four push-buttons on the front panel (see below) or via ASCII or Modbus communications. - Page 5 KEY MAP Plus This flowchart illustrates the operation of the POWER SERIES meter using the push-keys on the front panel.

Page 7: Changing The Potential Transformer (Pt) Ratio Setting
CHANGING THE POTENTIAL TRANSFORMER (PT) RATIO SETTING When you reach the PT setting the primary value is shown in the middle row and the secondary value in the bottom row. Press Set and the first digit of the primary value will begin blinking. -
Page 8: Changing The Current Transformer (Ct) Ratio Setting
CHANGING THE CURRENT TRANSFORMER (CT) RATIO SETTING When you reach the CT setting, the primary value is shown in the middle row and the secondary value is in the bottom row. Press Set and the first digit of the primary value will begin blinking. -
Page 9: Changing The Rolling Average Setting
CHANGING THE ROLLING AVERAGE SETTING The rolling average causes the displayed value to be an average of the number of samples to which this parameter is set. Increasing this setting will reduce digit bounce, but will slow the display response time. The analog output response time is not affected by this setting. When you reach the Average setting, press Set and the first digit will begin blinking. -
Page 10: Analog Output Scaling
Analog Output Scaling Plus The POWER SERIES has the option of analog output, which can provide an analog signal relative to the input of the meter. The relationship between the input and the output can be scaled by the user using the front panel. Analog Output 1 is always proportional to the value shown on the top display (Volts). -
Page 11: Changing The Analog Output Settings
CHANGING THE ANALOG OUTPUT SETTINGS When you reach the ‘out1’ (or ‘out2’ or ‘out3’) display, press Set and the value of HI will be displayed. Pressing Set again will cause the first digit to begin blinking. To move to the next digit press Next. Next will move you through all four digits and back to the first one, if necessary. - Page 12 The LO value is changed in the same way as the HI value: First digits, then the decimal point, then the multiplier, and finally the Confirm mode. In Confirm mode, with all the digits blinking, a press of the Set button will save all the changes and move you to the next setting. Note that the output settings have a precision of four (4) digits only.
