 Isolated RS-232 interface as standard
Selects 4k range and sounds audible tone for impedance <10. max="" input="" br=""> 265V DC or AC rms.
Diode Test
Displays junction voltages up to 3V at a test current of 1mA at 1V. Max. open
circuit voltage approximately 4V. Max. input 265V DC or AC rms.
Null (Relative): Stores current reading and subtracts it from future readings.
Hold: Reading is frozen until released.
T-Hold: Reading is frozen when it becomes stable.
Min/Max: Minimum and maximum readings are stored.
