Useful Function
55
It is possible to continue to change other setting items without
pressing the “FUNC.” key. In this case, press the “FUNC.” key to
confirm settings once changes are complete.
Variable Internal Resistance
* This function can be set for full-featured type "model name with F" only.
This function intentionally generates a voltage drop due to
load current when running in Constant Voltage mode.
This function is capable of approximating an internal
resistance of chemical batteries (during electric discharge)
and I-V characteristics of solar/fuel cells.
Setting Procedures
Press The Function “FUNC.” key.
The FUNC. lamp will light.
The Setting Item Number will be displayed in the Number
Display (voltage) and the parameter will be displayed in
the Number Display (current).
Select Item number 72 with the VOLTAGE dial.
Set the Internal Resistance value with the CURRENT dial.
Range(Ex)
HX-S-030-200G4F: 0mΩ to 150mΩ (Resolution: 2mΩ)
The range of internal resistance value and the resolution
depend on the number of parallel connected devices.
Refer to the table in page 93 (Setting Internal Resistance
Used for Digital Communication).
Factory default is 0mΩ (No Internal Resistance).
Press the FUNC. key again to finish.
Confirms settings and returns the Number Display to
measurement display mode.
MEMO
Variable Internal Resistance function is
restricted to only DC operations.
Not suited for approximating transient
phenomenon.
