App
Procedure
Preparation
Enable the AUTO V/I function that automatically switches from voltage measurement mode
to current measurement mode when the measured voltage reaches a specified value.
Set the GS610 as follows:
Setup Example of the GS610
SOURCE Output function Current output
Limiter value 3.6 V
Output mode DC
Output range: AUTO
OUTPUT CONTROL Trigger mode Internal
MEASURE Measurement function Voltage measurement
Integration time 200 ms
Measurement range AUTO
AUTO V/I ON
(auto switching of the measurement mode)
Store count Up to 65535 points.
Computation ON*
TIME Source delay 1 µs
Measurement delay 1 ms
Repeat period (of the internal trigger) 60 s
* Equation Example
If (I<=10E-3) then{← Condition statement for when the current value is less than or equal to
10 mA
@”:OUTPUT:STATS OFF”}←Turns the output OFF.
Source and Measurement
1. The GS610 generates constant current to the secondary battery and measures
the voltage.
2. When the voltage of the secondary battery reaches the charge voltage, a limiter
is activated, and the GS610 switches to current measurement mode.
3. Through the computation function, the GS610 turns the output OFF when the
measured current reaches a given value.
The source values and measured results are saved to a single file in the internal
memory of the GS610 (GS610RAM).
4. Transfer (Copy) the measurement result file from the GS610RAM of the GS610
to the PC via the USB.
5. Display the graph of the measured results using a general-purpose spreadsheet
application on your PC.

Time
In the discharge simulation, the pulse current sink operation of the GS610 can be used
to carry out constant current pulse discharge. The intermittent operation of mobile
devices can be simulated.
The maximum number of measured data points that can be stored is 65535.
