Constant Resistance Mode (Cr) - ITech IT8500plus Series User Manual

There are two ways to change the voltage:
 In CV mode, rotate Rotary knob.
 In CV mode, input value through number keys directly, press [Enter] to
confirm.
Steps
1. Press [CV], and then press [Shift]+[CV](Setup) to enter into the
parameters setting page.
RANGE=120.00V

3.2.3 Constant Resistance Mode (CR)

In constant resistance mode, the DC load will behave as a fixed resistance
value. As shown below, the load linearly changes the current value with the
rising of input voltage.
There are two ways to set the resistance value:
 In CR mode, rotate Rotary knob.
 In CR mode, input value through number keys directly, press [Enter] to
confirm.
Steps
1. Press [CR], and then press [Shift]+[CV](Setup) to enter into the
parameters setting page.
RANGE=7500.0Ω
CR
2. Set the maximum working resistance value, and press [Enter] to confirm.
RANGE =2000Ω
CR
3. Set the maximum working voltage value, and then press [Esc] to exit the
Note
Here, you can set only the current range, and other parameter settings are
used to edit the automatic test steps (described below).
In CV mode, the user can also set the minimum value of the current.
