Features:
Able to measure DC/AC voltage， resistance and perform continuity and insulation test.
Insulation test lock， to perform the insulation test until the test lock is unlocked.
Timer function， insulation test will stop automatically when the preset time is up.
Storing test data， to save 20 data and memory code from 00 to 19.
Reading test data， to display the data in memory.
Delete data， to delete selected data.
Data compare with the preset value limit.
Data holding function， to freeze the displayed value.
Relative measurement， to show the difference between actual value and relative base.
Able to select and review maximum， minimum and average value.
Able to measure the DAR and PI value.
Automatic power off to conserve battery power.
LCD display with analog bar and backlight.
Low battery indication.
Equipped with one tool bag for convenient carrying.
Solid case is shake-proof and skid-proof.

Note:
1. Lock function is invalid when timer function is selected.
2. When the input terminals is "Hi" and "Lo"， the overload protective voltage is 600V. When the input terminals is "V" and "COM"， the overload protective voltage is 1200V under the voltage test. In other test mode， the overload protective voltage in 250V.
