Fig 28. Auto pause/Restart setup

Fig 29. Hardware setup

“First Ts”: the measurement time for each group, the time can be set by user or choose
between 1min, 5mim, 10min, 20min, 30min and 1hour.
“Total”: the total groups of continuous measurement. The number can be set from 1 to
1440.

Note

：

When enter restart interface, “Restart clock” is displayed on the bottom row.

“Mode”: working mode of auto pause or restart setup which can be chosen between N/A
and Clock. When N/A is chosen, the instrument will not pause or restart. When Clock is
chosen, the instrument will auto pause or restart when the internal clock reaches at
the fixed time.
“Date”: the fixed date for auto pause/ restart
“Time”: the fixed time for auto pause/restart
You can move the cursor on Year, Month, Day, Hour, Minute and Second either, and use
or key to adjust the time. When a parameter reaches its end, it displays “**”
which means the parameter does not participate in comparison when auto-on or
auto-off. The instrument can switch on or off once an hour, once a day, once a month……
It is suggested to use Auto pause or Restart function together with Timed Activation
function to make automatic measurement.

Move the cursor to the second and third row under “setup 2” interface and press
key, then enter Auto pause / Restart setup interface.

Move the cursor to the “hardware” on page 2 under “setup 2” interface. Press then it
displays as follows:

The first line shows the amplitude of AC output and frequency weighting. The second
row shows whether the instrument will turn off automatically for a long time without
any operation. The third row shows the indicator lamp light specified threshold. The
fourth row shows the baud rate of serial port. The cursor can be moved to “AC”, “W”,
“Auto-off”, “Limit” and “Baud rate”.
