5-8 Application Operation PLZ-U
5.5 Elapsed Time Display and Auto Load Off
Timer
You can achieve two functions that are convenient for the discharge test of batteries
by combining the following four functions: elapsed time display, UVP (undervolt-
age protection), load-off voltage display, and auto load off timer.
Fig. 5-7 Elapsed time display and auto load off timer
Time measurement from the start of discharge to the cutoff voltage.
The time from when the load is turned on until the load is turned off due to the trip-
ping of the UVP is measured.
■
Procedure
1. Set the UVP voltage.
2. Switch to the elapsed time display.
For the procedure of setting the UVP voltage, see section 4.4.3, “Setting the Trip
Points.” For the procedure of switching the display, see “DISP key” on page 3-9.
Voltage measurement after a certain time elapses from the start of
discharge
After the load is turned on, the load is turned off using the auto load off timer. The
voltage that is present when the load is turned off is measured.
■
Procedure
1. Set the auto load off timer.
2. Switch to the elapsed time display.
3. Switch to the load-off voltage display.
For a description of the auto load off timer, see section 4.2, “Load On/Off.” For the
procedure of switching the display, see “DISP key” on page 3-9.
