Cursor keys
To exit the menu during
operation, press ESC
located above the soft
keys.
In the procedural
explanation below, the
phrase “press the cursor
keys” may be used. This
phrase refers to the
procedures for selecting
items and entering values
and character strings. For
details on the procedures,
see section 3.14.
• Selecting the Target Element
1. Press ELEMENT to select the target element. The corresponding element
indicator above the key illuminates.
• Selecting the Voltage Mode
2. Press VOLTAGE RANGE MODE to select one of the modes from RMS to RMEAN.
3. Repeat steps 1 and 2 to select the voltage mode of all elements.
• Selecting the Current Mode
4. Press CURRENT RANGE MODE to select one of the modes from RMS to
RMEAN.
5. Repeat steps 1 to 4 to select the current mode of all elements.
Explanation
• The voltage and current modes can be selected from the following four modes.
• RMS: True rms value
• MEAN: Rectified mean value calibrated to the rms value
• DC: Simple average
• RMEAN: Rectified mean value
• The initial setting is RMS. For the method of computing the voltage and current in
each mode, see appendix 1.
• When the independent setting of input elements is OFF, the element switches
according to the wiring system.
• To measure the RMS and MEAN of voltage simultaneously, use the user-defined
function. For details, see section 5.4.
• The voltage and current mode selections are invalid in wide bandwidth harmonic
measurement mode and IEC harmonic measurement mode. In this case, the total
value of the rms values of each order in the range between the maximum and
minimum values of the measured order specified in the harmonic measurement
(option) menu is displayed.
• The voltage and current mode selections are invalid in voltage fluctuation and flicker
measurement mode.
