High Resolution Mode
Normally, set the main setting of the source voltage or current at 5.5 digit resolution (4.5 digit resolution
for 30 A range). In high resolution mode, you can set it at 6.5 digit resolution (5.5 digit resolution for 30
A range).
In normal resolution mode, use the five main setting dials to set 5.5 digits. In high resolution mode, use
the five main setting dials and deviation dial 1 to set 6.5 digits.
In high resolution mode, the output divider, deviation output, sweep, and scaling features cannot be
used. Further, high resolution mode cannot be used for temperature or resistance ranges.
Turning the Beep Sound On and Off
Beeps are used to indicate the operation status of the device. You can turn it on and off from the
SETUP menu.
You can turn the beep sound on or off for the following notifications. You cannot change the volume.
• When a voltage greater than or equal to +150 V or less than or equal to –150 V is to be output,
regardless of the output on/off state
• When a sweep operation is held
You cannot turn off the beep sound for the following notifications.
• When the cooling fan stops (error code: E.901, E.907)
• When an abnormal temperature is detected (error code: E.902, E.903)
• When an internal power supply error is detected (error code: E.904, E.905, E.908)
• When an error is detected during a self-test executed at power-on or by some other operation (error
codes: E.911 to E950). However, you can turn off the beep sound for these errors by performing the
