96034 or 96035: Current range is selected using the switch on a clamp-on current probe.
Function Keys
F1 F2 F3 F4
NOTE
• The current ranges to be selected differ depending on the clamp-on current
probe to be used.
• For measurements of multiple loads, a current range can be set for each load.
For this, press the F2 key (LOAD CHANGE) to select the load for which you
wish to change the current range and then set the current range.
• If the wiring system is 1P3W3I or 3P4W4I, you cannot use the A RANGE key to
set the current range of I4. To set this current range, move to the SETUP screen
and then set it.
• If the wiring system is a Scott connection, a current range can be set
separately for the three-phase three-wire and single-phase three-wire sides.
For this, press the F2 key (3P3W or 1P1W) to select the wiring for which you
wish to change the current range and then set the current range.
• If the result of "power rating ⫻ VT ratio ⫻ CT ratio ⫻ 1.3" exceeds 999.9 TW,
the current range cannot be changed. To change the current range in this case,
modify other settings (wiring, voltage range, clamp-on probe type, VT ratio,
and/or CT ratio) and then change it.
TIP
• A current range cannot be set during integration measurement (including when on
standby).
• A current range cannot be set in the VOLT. QUALITY or WIRING DIAG. screen.
• If integral measured data has not been cleared, the current range cannot be changed.
To change the current range in this case, press the F5 key (HOLD/CLEAR) for more
than 3 seconds on the MEASURE screen to clear integral measured data and then
change it.
