1.2 Dial and Switches
Main Setting
Section
The main setting section is used to set and display the output range of voltage, current, resistance,
and temperature. The main setting set using the SCALE switch (explained later) with the MAX indicator
turned on is the maximum value (MAX) of the output range and that with the MIN indicator turned on is
the minimum value (MIN) of the output range.
POLARITY switch
Sets the polarity
Main setting dials
Use the main setting dials to specify the main settings. From the left,
the dials are the 1st, 2nd, 3rd, 4th, and 5th main setting dials.
Use each main setting dial to set the corresponding digit value, shown
by the frames.
Carrying over and borrowing occurs automatically within the
selectable range.
For instructions on how to use the SETUP menu, see section 4.2.
Main setting display
Large 5.5-digit 7-segment LEDs are used.
The main setting including the polarity is
displayed.
Polarity
display
Unit display
Two 5×7 dot matrix LEDs are used. Unit is
displayed according to the range set with
the RANGE dial.
SCALE Section
Use the SCALE switch to select the maximum value (MAX) and minimum value (MIN) of the output
range. Output divider, deviation, and sweep features operate assuming (MAX – MIN) to be 100%.

Non Zero indicator
MAX (Main setting (MAX))
Flipping the SCALE switch up turns the MAX indicator on. Use the POLARITY switch and the main
setting dials in this condition to set the maximum value of the output range. When the output is
turned on, the specified voltage, current, resistance, or temperature is generated from the output
terminals.
MIN (Main setting (MIN))
Flipping the SCALE switch down turns the MIN indicator on. Use the POLARITY switch and the
main setting dials in this condition to set the minimum value of the output range. When the output
is turned on, the specified voltage, current, resistance, or temperature is generated from the output
terminals.
Setting a value other than ±0 (zero) causes the Non Zero indicator to turn on.
