the

buttons. Select Σ to display total for all phases.

NOTE: The display is automatically adjusted for a display in W, VA, VAR or kW,

kVA, kVAR. It is possible to switch to other display modes without stopping the

totalization.

NOTE: Incorrect probe installation on phases (black on B phase or C phase) or

arrow on probe facing in the wrong direction (towards line instead of load) will

result in inaccurate data. Negative data on one or more phases may be an indica-

tion of this.
