AUTORANGING INSULATION TESTER instruction manual SAFETY INFORMATION Read the following safety information carefully before attempting to operate or service the meter. The circuit under test must be de-energized and isolated before connections are made except for voltage measurement. Circuit connections must not be touched during a test. After insulation test, capacitate circuits must be allowed to discharge before disconnecting the test leads.

AUTORANGING INSULATION TESTER instruction manual V. MEASURING FUNCTIONS 1. ACV Function: Turn function selector to voltage range. Connect black test lead to Lo terminal and red one to the Hi terminal. Connect test lead to the test circuit in parallel. One can hold the reading by pressing the HOLD key.
AUTORANGING INSULATION TESTER instruction manual Manual Mode: Press and hold the test key to active the test voltage source. A periodic beeping will warn the high voltage output. Release the test button to stop the test voltage output. A series of beeping with shorter period indicate the discharging in progress.
AUTORANGING INSULATION TESTER instruction manual VII. BATTERY CHANGING When appear on the LCD, the battery need to be replaced with new ones. To replace the battery the user should turn the function selector to OFF position. Then the user needs to open the battery compartment cover with a screwdriver.
