Selecting the desired range
Press the range key to select the desired range. The lamp for the selected range key will light up, and the dis-
play value will change to reflect the selected range.
3.2.4 Selecting the Voltage and Current Ranges
When input exceeds 1,000 V, ±1,500 Vpeak, or 70 A, ±100 Apeak
The maximum input voltage and maximum input current are 1,000 V, ±1,500 Vpeak, and
70 A, ±100 Apeak. If the maximum input voltage or maximum input current is exceeded,
immediately halt measurement, deactivate power to the measurement lines, and dis-
connect the cables from the instrument. Continuing measurement with maximum input
exceeded will damage the instrument and cause bodily injury.
Do not input a voltage or current in excess of each measurement range. Doing so will damage
the instrument.
• When using a wiring mode other than 1P2W, the voltage and current ranges will be standardized using the
CH1 settings.
• Allow the following amount of time to elapse before reading measured values after changing the range:
• When the frequency of input set to the synchronization source is 10 Hz or greater
Approx. 0.6 s
• When the frequency of input set to the synchronization source is less than 10 Hz
See: "3.2.7 Setting the Timeout" (p.55)
• Channels for which the range has changed will use the invalid data display [- - - - -] until the data is
updated.
• When measuring frequencies of 10 Hz or less, it is necessary to set the timeout to a value other than 0.1 sec.
See: "3.2.7 Setting the Timeout" (p.55)
• When using external current sensor input as the current input method, only the 10 A, 20 A, and 50 A keys
are valid for selecting the current range. Pressing another range key will cause TYPE1 or TYPE2, indicat-
ing the type of external current sensor, to be displayed, and the range will not be changed.
• Ranges cannot be changed while integration is being performed or during display hold or maximum value/
minimum value hold operation.
