Version: 1/05/I/1211/ C
Application
Continuity Test
It is Analog Digital Multimeter which measures VAC, VDC,
VAC+DC,Frequency, mA DC, mA AC+DC,Resistance, continuity,
Diode, Farad, AC current measurement.
This permits testing for short circuit and open circuit. In
addition to the display, a facility of sound signal is available.
Product Features
MIN/MAX Value Storage
In addition to the display of the actual measured value, the minimum
or maximum value can constantly be updated and stored.
Indication of negative values on the analog scale
Automatic Data Hold
The DATA HOLD function makes it possible to hold the digitally
displayed measured value . It is ensured that no freak value but the
actual measured value is held in the case of rapid changes in
measured quantities . The held measured value appears on the
digital display. The actual measured value continues to be shown
on the analog scale.
Autoranging / Manual Range Selection
The measured values are selected with rotary switch. The
measuring range is automatically matched to the measured value.
The measuring range can also be selected manually via the
AUTO/MAN push button.

Input Impedance
Overload Warning
A sound signal indication violation of the overload limits.
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.
Meas. Measuring
Temperature measurement
It is possible to use RISH multi 11 in direct connection of
temperature sensor Pt 100 / Pt 1000. The meter automatically
detects the type of sensors connected to it & displays directly
measured temperature .
Power Economizing Circuit
The meter is switched OFF automatically when the measured value
remains unchanged for about 30 minutes and no operating control
was operated during this time. The disconnection facility can be
disabled.
Protective Holster for rough duty
A holster of soft rubber with tilt stand protects the meter against
damage in the case of shock and drop. The rubber material makes
for the meter to stand firmly even on vibrating surface.
Calibration
RISH multi is automatically calibrated with respect to Fluke 5500 /
Wavetek 9100. Every multimeter is provided with the Test Certificate
which is traceable to National / International standards. All the meters
can be recalibrated at the Rishabh Instruments.
