HIOKI 3154 Digital Meg-Ohm HiTester
Insulation resistance testing for system measurement
Six test voltages from 25 V to 1000 V. Stores 10 setting states. Comparator and timer functions facilitate easy testing in accordance with various safety standards. Start, Stop, or other configuration external control is provided. Measuring terminals in rear panel is convenient to buid system.
Note: Main unit cannot operate alone. Please select and purchase the test lead options appropriate for your application separately.
Basic specifications (Accuracy guaranteed for 1 year)
Measurement items : Insulation resistance (Applied DC voltage method)
Testing voltage / measurement ranges (Auto / Manual) : 25/ 50V: 2.000/20.00/200.0 MO,
100/ 250/ 500/ 1000V: 2.000/ 20.00/ 200.0/ 2000MO (at 500 or 1000V testing, up to 4000MO)
Basic accuracy : ±2% rdg. ±5 dgt. : at 25/ 50/ 100V [0 to 20MO], 250V [0 to 100MO], 500/ 1000V [0 to 999MO]
Measurement speed : Fast: 10 times/s, Slow:1 time/s, selectable, Response times: less than 0.5 second
Display : LED
Internal memory : Testing voltage, Limit level value of comparator , Testing mode, Beep sound of decision, Testing time, Delay time, Resistance range, Measurement speed
Number of memory: Max. 10 (External control to save or load)
Comparator setting : Key press: Select lower limit value from designated options
RS-232C: Set optional lower limit value within measurement range
Judgement process : PASS: Measurement value = lower limit, FAIL: Measurement value < lower limit, Beep sound, PASS/FAIL display, signal output to external I/O
Test duration timer : After measurement START is initiated and waiting time (0.35s max.) + designated test duration elapses. Test duration: 0.5 to 99 s
