Integration Auto Calibration On/Off (Auto Cal)
Ordinary zero-level compensation takes place when the measurement range or line filter is changed, but you
can also automatically calibrate the zero level during integration.
• ON: Zero-level compensation takes place automatically approximately once every hour during integration.
• OFF: Zero-level compensation does not take place automatically during integration.
When integration auto calibration is on and zero-level compensation is in progress, the power or current value
measured immediately before is integrated.
Watt Hour Integration Method for Each Polarity (WP ± Type)
Setting (Setting)
You can select the method for setting the integration method from the following options.
• Each (Each): Set it separately for each input element.
• All (All): Set it for all installed input elements at the same time.
Element1 to Element7
Set the integration method to one of the options below.
• Charge/Discharge (Charge/Discharge): Measure DC watt hours (for each sampled data item) by polarity.
• Sold/Bought (Sold/Bought): Measure AC watt hours (for each sampled data item) by polarity.
For information about the equations used in each method, see appendix 1 in the Getting Started Guide, IM
WT5000-03EN.
Current Mode for Current Integration (q Mode)
Setting (Setting)
You can select the method for setting the current mode from the following options.
• Each (Each): Set it separately for each input element.
• All (All): Set it for all installed input elements at the same time.
Element1 to Element7
You can select the current mode from the following options. For information about the equations used in each
current mode, see appendix 1 in the Getting Started Guide, IM WT5000-03EN.
• rms: True rms value
• mean: Rectified mean value calibrated to the rms value
• dc: Simple average
• r-mean: Rectified mean value
• ac: AC component
When the current mode is dc, the polarity (+ or -) is displayed.
