When
T Min
is set to zero second, it means the unit is on real time and the length of time lapsed is on
the left hand side of the Time Minimum.
T Len
is the length of time lapsed starting from the Time
Minimum. In the above example, T Min is set to 320 second and T length to 60 second, the display
shows the output data starting at 320 seconds ago and ending at the 380 second mark.
Figure 8.4.4b The time frame of Data Log
8.4.5. Internal Timed Program
The PC Interface remote mode really eliminates the tedious process in keying in groups of entries on
the power supply. Because all the data are displayed together in the monitor, possibility of wrong entry
is greatly reduced. Data of different groups can be classified, stored, exported and retrieved for use at
any time. Furthermore, retrieved data will be in red colour if they exceed the preset limits of voltage in
Upper Voltage Level or Current Limiting values. The operation principle of Saving, Exporting, Filing,
Deleting and Printing are the same as the Data Log Function.
Clear Table
........... Delete all data in the Display Table and ready for new data entry.
Save To PS
..............Transfer data from Display Table to the Power Supply.

entered.
Operation
1. Clear old data in the power supply by first click [
Clear Table
] then click [
Save To PS
].
2. Check if no data in power supply by click [
Read Fro PS
].
3. Enter data in the table using the 'Up Down Left Right' keys of your PC keyboard for new locations
4. Data exceed the rated voltage and current will not be accepted.
5. Voltage exceed set UVL (Upper Voltage Limit) will not be accepted.
6. If retrieved or entered data exceed preset Upper or Lower Limit setting of voltage/ current/time, the
data will becomes red in colour.
7. Transfer set data to power supply by clicking [
Save to PS
].
8. Click [
Read Fro PS
] to initiate the [
Run
] Command.
9. Set number of desired [
Running Cycle
] and click [
Run
].
8.4.6. Internal Preset Memory
The operation principle is the same as Internal Timed Program. To activate the selected preset values,
click on the box of the [
Select
] column then click [
Run
]. If retrieved or entered data exceed present
Upper or Lower Limit Setting of voltage/current/time, the colour will become red in colour.
8.5. Running the software using RS-485 Interface
Note
Before running the application software, you must have installed and connected your power supplies
to the PC via RS-485 as Figure 8.2a and b on page 16.
