2. FEATURES
MODEL-3005A/3007A are microprocessor controlled insulation-continuity
testers.
● Designed to safety standards:
IEC 61010-1 Overvoltage CAT III 300V Pollution Degree 2
IEC 61010-2-31 (Safety requirements for hand-held probe assemblies)
● Display with back light function to facilitate work at night or dimly lit
locations (Model 3007A only)
● Bar graph to indicate measured results
● Strap belt to make both hands' operation easier
● Live circuit warning indication and buzzer
● Auto discharge function
When insulation resistance is measured, electric charges stored in
capacitive circuits are automatically discharged after testing. Discharge
can be checked with live circuit warning.
● Auto power off function
To prevent the instrument from being left powered on and conserve
battery power, the instrument automatically turns off approx. 10 minutes
after the last switch operation.
● LOK mode (Model 3007A only)
The test current is removed once a stable reading is reached to prevent
unnecessary battery consumption.
