A Wide Frequency Range Lets You Work on a Variety of Different Applications

• Low-frequency Equipment
  Low-frequency measurements starting at 0.5 Hz
  Low-frequency measurements starting at 0.5
  Hz can be used with evaluations of
  cycloconverter and when a motor are started
• Commercial Power Supplies — 0.1%
• Inverters — 100 kHz power frequency range
  Now you can obtain more precise measurements on high-frequency equipment such as inverters.

Capture a Variety of Signal Types

• Surge current and maximum load state
  — MAX hold function for voltage, current, & power 3
  This function lets you keep, on the display, voltage and current peak values, voltage and current rms values, and maximum values for active power, apparent power, and reactive power
• Half-wave Rectification, Intermittent Control, Distortion Waves
  —Measurement of DC components
  In addition to using DC inputs, you can obtain precise measurements of signals containing DC components, such as intermittent signals and half wave rectification signals
• Constantly changing signals
  — Quick response with display updating as fast as every 0.1 second With measurement intervals as short as 0.1 second, you can capture transient phenomena with a fine level of detail. You can also reduce the time per measurement for increased through put in production testing
• Noisy Signals
  — Line filter function (fc = 500 Hz)
  This function lets you measure fundamental wave rms values for inverter output voltages

Powerful Tools for Energy Measurement

• Extended Energy Measurement Applications
  — Maximum integration time: 10,000 hours 3
  Time can be set between 1 second and 10,000 hours (416 days) in 1- second increments.
• Battery equipment applications
  — Integrating power measurement by polarity Power and current values can be integrated separately for positive and negative polarities. Integrated values are shown with the decimal point moving according to the integrated value.
• Extended Energy Measurement Applications
  — Maximum integration time: 10,000 hours 3
  Time can be set between 1 second and 10,000 hours (416 days) in 1- second increments.

Applications for a Variety of Add-on (Options )

• Large-current Measurement Using Current Clamps
  — External input for current sensor
  Select either 50/100/200 mV or 2.5/5/10 V.
  A current clamp lets you measure currents without needing to disconnect the power supply circuit wiring.
• Power Supply Harmonic Measurements Calculate voltage, current, reactive power, content ratio, and phase angle relative to fundamental frequency for up to 50 orders. This option is well-suited to power supply environment evaluations. Measurement time is approximately GP-IB/serial interface (RS-232-C) 90% shorter than in former models
• GO/NO-GO Evaluations on Testing Lines
  — 4-channel comparator function
  A 4-channel relay contact output (normal-open and normal-close pair) lets you do GO/NO-GO evaluations on production and testing lines.
• Recording to a Recorder
  — D/A Output
  This option lets you output a variety of measurement data, such as voltage, current, and power measurements, with ±5 V rating, for recording on a recorder.
  The recorder can then be used to check changes in data over time.
• Online Power Meter Control and Recording
  — GP-IB/serial (RS-232-C) interface
  This option lets you control the power meter through a PC, or save data to a PC.

WTViewer Software
Easily Acquire and Manage Power Measurement Data form Your PC

WTViewer is a software application that allows you to load numeric and waveform data measured with the WT210 Power Meter to a PC via GP-IB or serial (RS-232-C) communications. It lets you view the measured data then save it to hard disk. Using GP-IB allows you to connect up to four WT210s simultaneously

• Numeric Data
  WTViewer can display the voltage, current, power, and phase of the measured data simultaneously. It can display up to 250 data items on the screen at once.

• Waveform
  WTViewer lets you monitor voltage and current waveforms on your PC screen. The waveform display function lets you check the voltage and current phase angle, waveform distortion, and peak shapes.
  • The WT210 requires an harmonic analysis option (/HRM) for waveform display and harmonic measurement.

• Harmonic Measurement
  With WTViewer, you can numerically or graphically display the results of measured harmonics of voltage, current, power, and phase harmonics up to the 50th order.

• Trend
  Various types of measured data can be displayed in a trend graph. You can survey chronological changes in such phenomenon as the variations in the supply voltage
  and current consumption. Harmonic trends can also be displayed.

• Settings up WT210 from Your PC
  You can enter WT210/WT210 settings such as the wiring method, range, filters, and scaling from your PC. These settings can be saved on the PC then loaded back in all at once when needed.

• Converting Data to CSV
  Waveform and numeric data can be saved on the PC. From the PC you can create .wtd files that can be loaded by WTViewer for WT210/WT210, or .csv files that can be imported into Excel.
