5.1.2.1 Manual recording
Push ‘MEMO’ button, and
MEMO No. symbol will be
lit up and data No. flash.
Switch to mode of
setting time interval,
and time No. will flash.
Use ‘Enter’ to
confirm the
selected data No.
Tips
Note 1: If the held data is displayed, the log-recording mode cannot be accessed, and therefore you need to push CLEAR
button to clear the held data before proceeding to the next step.
Note 2: The mode of log-recording cannot be accessed under the mode of step-voltage measurement or the mode of
temperature compensation.
Note 3: When a value of temperature or humidity is held and if you push ‘SAVE’ button, it will switch to the interface for saving
standard data.
Note 4: If USED symbol is displayed for a certain data number, it indicates that there is already data saved under this number;
because data cannot be overwritten under log-recording mode, you need to delete the saved data before saving new
data.
Note 5: When there are 10 groups of data saved in the log record and if ‘SAVE’ button is pressed, FUL will be displayed and
alarming indicator will appear. If you wish to save more data, you need to delete the previous data and then press
“SAVE” button to access the log record mode.
1. Start the insulation resistance measurement, and the first data will be obtained after the first specified time interval.
2. Insulation resistance measurement will stop under the following three circumstances:
If time reaches the Max. recording time; or
If time reaches the set period of time in the timer; or
If ‘measure’ button is pushed.
Data number starts flashing at the end of measurement, while data has not been saved at this moment.
3. Temperature measurement can be carried out when necessary, which can be skipped usually.
Temperature and humidity values that are measured with an external thermometer and hygrometer can also be entered into
the tester.
Tips
Note 1: If the measurement stops before the first time interval, then log-recorded data will not be obtained, while data number
will be displayed.
Note 2: If LobAt is displayed and the data number is flashing after a measurement, it indicates that either the battery power is
insufficient or power is turned off, and data will be saved.

mode
Push ‘ENTER’ to return to standby
mode, and log-recording is effective.
5.1.2.4 Testing
Procedures
Push ‘ENTER’ button, and MEMO No. symbol will be turned off after flashing and log-recorded data will be saved in the
memory. In case the memory is damaged, ‘Err’ will be displayed on LCD with 3 warning beeps, and then ‘Err’ will disappear
after 1 second.
Tips
Note 1: The tester cannot record the following data: ambient temperature under which insulation resistance measurement is
carried out, the external voltage during a voltage measurement, and the leak current data which is read as resistance
data.
5.1.2.5 Saving data to the memory
Use ‘ ’,‘ ’
button to select
data No. lr0 - lr9.
