Insulation resistance with analog/digital multimeter measuring Vac Vdc Vac+Vdc Hz mADC mAAC+DC Ohm continuity, Diode Farad Temperature AC I measurement with clip-on sensor with measureemnt of 3GOhm with test V upto 1000V, Functions of Min, Max, Auto off.
Features:
- Insulation resistance measurement up to 3G Ohm:Insulation resistance measurement up to 3G Ohm with Test voltages selection: 50 V, 100V, 250V, 500V and 1000V.
- Route mean square value with distorted wave form: Measuring principal employed permits the measurement of rout mean square value (TRMS) OF AC quantities and mixed quantities (AC and DC) regardless of wave form.
- AC Current measurement with clip-on sensor: Current measurement up to 300A with clip-on sensor having ratio 1mV/10mA.
- Min/Max Function: By pressing min/max button instrument will start recording minimum and maximum readings.
- Temperature measurement: Temperatures from -200 to 800 ºC using pt100 and pt 1000 sensors.
- Auto Power Off: In order to save the power of the Batteries, the meter will automatically shut OFF if it detects no activity for 10 minutes.
- Continuity test: This permits resting for short circuit and open circuit. In addition to the display, a facility of sound signal is available.
- AUTO and MANUAL ranging modes: In AUTO ranging mode the instrument automatically selects the range with best resolution depending on the applied input. In MANUAL ranging mode range is user selectable using MAN key.
- Indication of negative values on the analog scale: When measuring DC quantities, also negative values are shown on the analog scale so that variations of the measured value can be observed at the Zero point.
- Protection from dust and water: IP50 (Instrument) IP20 (For terminals) as per IEC60529
- Applicable International Safety standards: 1000 V CAT II/600V CAT III as per International Safety standard IEC 61010-1- 2001 and IEC 61557.
- Signaling in the case of a blown fuse: The display shows “FUSE” in case of blown fuse.
- Automatic blocking socket (ABS): The automatic terminal blocking system prevents incorrect connection of test lead and incorrect selection of measurement quantity, which provide safety to the user.
- Interface and software RISH com 100: The multimeters are fitted with a serial RS-232 C interface via which the measured values can be transmitted to a PC. These values, electrically isolated, are transmitted to the attachable interface adaptor with infrared light through the case.
- Analog Scale: Analog scale that updates at the rate 20 times/sec to observe fluctuations in input.
- Continuous On Mode: In this mode, AUTO POWER OFF is disabled.
- DATA Hold Function: By pressing DATA HOLD button, reading on the display can be latched for Hands free operation.
- NULL ZERO Correction for Resistance: For Low ohm measurement, the lead resistance can be compensated by pressing the shift key (Yellow Key)
- NULL ZERO Correction for Capacitance: Null zero connection for capacitance. For nF range, stray capacitance can be compensated by shift key (Yellow Key)
- Diode Measurement: For testing diode and transistors, diode measurement function is available.
- Display with Backlit: For clear visibility in dark conditions, RISH MIT 30 is featured with backlit.
