Programmable DC Electronic Load 63600 Series Operation & Programming Manual
4-16
4.4.6 Setting CZ Values
When operate in CZ mode, the VFD displays CZ mode.
There is only one impedance range for CZ operation. The current is always in high range.
ALL resistance levels are programmed in
Ω. The C
L
is in
μF, and the Ls is in μH. The
following examples show how to set the CZ values of Load module for model 63630-80-60.
1.
Set the Level of the equivalent parallel load capacitance C
L
The setting range is from 30
μF to 50,000μF. There are 15,000 discrete steps in the
range. Press the key to enter into the editing mode. Turn the Rotary knob to
change the display value to 2,000
μF, then press
key to confirm.
C
L
: 2000
μF
The user may use or key to change the cursor position to different digit of
data, then turn the rotary knob to change the value of that digit.
If the user does not use or key to display the cursor, then resolution of the
value changes according to the rotary knob turning speed
2.
Set the Level of the equivalent parallel load resistance R
L
The setting range is the same as the CR mode high range of the Load model. There are
15,000 discrete steps in the range. Press the key to enter into the editing mode.
Turn the Rotary knob to change the display value to 3
Ω, then press
key to
confirm.
R
L
: 3.0
Ω
3.
Set the Level of the equivalent series inductance Ls
The setting range is from 0.1
μH to 20μH. There are 15,000 discrete steps in the range.
Press the key to enter into the editing mode. Turn the Rotary knob to change
the display value to 0.1
μH, then press
key to confirm.
Ls : 0.1
