Press “HOLD” (INTV) for adjusting the next item, then press “HOLD” (INTV) to save the setting value. In the course of
setting up, If you want to exit from this mode and do not save any value, press “ ” button to end.
NOTE:
The time interval mode is minute and second.
4.11 DATA RECORDING
Press “REC” button, the meter will start recording according to the set time interval. After a set time interval will have a group of
data. At the beginning, REC will be shown on the left side of the LCD; press the “REC” button again will make the recording stop.
A whole data recording is finished.
When the memory is full, REC will be flashed per a second. If user wants to
check the memory content, should use RS-232 connecting line and the software
to send the content to the computer.
If you want to clear the memory, power off the meter, then press and hold “REC”
button and then press “ ” button and hold at least 2 seconds till CLR is shown
on LCD (see Fig. 6), which indicates that the memory is being cleared and finished
clearing till CLR dispears.

INSTRUCTION MANUAL
OPERATING INSTRUCTION
NOTE:
• LED is the main source of back light. Its working current is large, often use back light will shorten the battery life, you’d better
not to use the back light so frequently unless it’s necessary.
• When the battery voltage is less than 7V, it will show “ ”. But if you use back light at the same time, maybe “ ” will
come up even if the battery voltage is more than 7V, because the working current is higher and the voltage will decline.
(When “ “ shows, the accuracy of the measurement can not be assured.) You need not replace the battery. When you
use normally (back light is not using), “ ” will not show up. You need replace it till “ ”show again.
4.13 AUTO POWER OFF:
When the meter is power-on, there will be shown on the left side of the LCD, which means the meter will be power-off after
30 minutes if no key operation and no RS232 communication and no recording.
One may press and hold "HOLD" button and then power on the meter. There will be two successive beeps to indicate that auto
power off is disabled and the will not be shown up.
4.14 DIGITAL OUTPUT:
The Digital Output is a 9600bps N 81 serial interface.
