Figure 2-9 Main Interface of CR Mode
In CR mode, you need to set the following parameters: RES, Range, V_Limit,
C_Limit.
Set RES
The constant resistance value in CR mode. The resistance unit is: Ω or kΩ.
(1) In the main interface, press RES to switch the parameter focus to "RES".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For
setting methods, refer to the descriptions of the help information or refer to
the descriptions in "Parameter Setting Method".
Set Range
Working range for the resistance in CR mode. Two resistance ranges are
available: low range (0.08 Ω to 15 Ω); high range (2 Ω to 15 kΩ)
(1) In the main interface, press Range to switch the parameter focus to
"Range".
(2) Press Range to switch the resistance working range. You can also use the
Left/Right arrow key or the knob to switch it.
Note:
 The low range provides better resolution and accuracy at low resistance
settings.
 If the set resistance value is greater than the maximum value of the low
range, you must select a high range.
CAUTION
Before switching the resistance range, please disable the channel
input to avoid causing damage to the instrument or the DUT.
Set V_Limit
The upper limit of the voltage working in CR mode. The default unit for V_Limit
is V, and it ranges from 0 V to 180 V.
(1) In the main interface, press V_Limit to switch the parameter focus to
"V_Limit".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For
setting methods, refer to the descriptions of the help information or refer to
the descriptions in "Parameter Setting Method".
