Data storage

3,000 sets, press HOLD to hold the data ,number and store automatically(power failure or battery replacement will not cause  data missing)

Line voltage

Test for lines bearing voltage below 60kv (insulating rods with five knots must be used)

Data hold

Press HOLD to hold the data, and sign of “Hold” appears; press it again, holding will be canceled.

Data search

Press HOLD and POWER to enter the mode of data search.
