"3.10.3 When o.r (over-range) Is Displayed" (p.113)
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.
3.2.3 Selecting the Voltage and Current Ranges
When input exceeds 1,000 V, ±1,500 V peak, or 30 A, ±100 A peak
The maximum input voltage and maximum input current are 1,000 V, ±1,500 V peak, and
30 A, ±100 A peak. 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.
• 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 sec.
• When the frequency of input set to the synchronization source is less than 10 Hz
See: "3.2.6 Setting the Timeout" (p.54)
• If the range changes, the invalid data display [- - - - -] will be shown 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: "3.2.6 Setting the Timeout" (p.54)
• When using external current sensor input (TYPE.1 or TYPE.2) as the current input method, only is
valid for selecting the current range. Pressing another range key will cause [tyPE.1] or [tyPE.2], indicating
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 operation.
Voltage range Current range
Default settings: 300 V voltage
20 A current
Two or three ranges are assigned to each
range key.
