Why Doesn't the Theoretical Power Value Match the Measured Power Value?
Check for differences in the specifications or features of the instruments. For values that do not match when inputting a 50/60 sine wave Check whether the value is within the specifications (error) of each power meter...

How do I Retrieve Data From the Instrument Only When it is Updated Using IEEE488.2 Commands?
You can use the "STATUS:ESSR?" command to access the extended event register and determine whether the data was updated. You can judge the data update status by referencing bit 0 (UPD) of this register. However to do so,...

Can I use the Store Function to Record Waveform Data on the WT1800?
THE WT1800 and WT500 STORE function can only be used to record NUMERIC data. The WT1600 and WT3000 STORE function can be used to record both NUMERIC and WAVEFORM data. ...

Why are the Measured Values for VAR and ΣVAR Unstable?
Check the Synch Source and Frequency Filter settings When a single-phase signal being measured fluctuates around power factor of 1.Slight fluctuations in the measured values of voltage, current, and power can cause a la...

Why are the Measured Values for Voltage, Current, and Power Unstable?
Check the "Sync Source" and zero cross filter (frequency filter) settings. For the WT3000, "Sync Source" setting is irrelevant if the data update rate is 250 ms, 500 ms, 1 s, or 2 s. Sync Source SettingIn principle, if t...

Why is the Theoretical Calulated Three-Phase Apparent Power Values (ΣVA and ΣS) Different From the Measured Values?
This is due to measurement and calculation error, or differences in calculation methods. On the WT, the three-phase apparent power (ΣS) equation is calculated under the assumption of a balanced condition (the absolute...

Why Doesn't the Voltage, Current, Power Values Measured on Power Meter A Match Those From Power Meter B?
Check for differences in the specifications or features of the instruments. For values that do not match when inputting a 50/60 sine wave Check whether the value is within the specifications (error) of each power meter...

Why are the Measurement for Voltage, Current, and Power in Normal Mode Different Than Harmonic Mode?
The difference in measurement values can be attributed to the difference in calculation methods for normal mode and harmonic mode. The voltage, current, and power in normal mode are displayed as the total of the measu...
