Automatic Terminal Blocking System (ABS)
The automatic Terminal blocking system prevents incorrect connection of the test leads and incorrect selection of the measured quantity. This reduces danger to the user, the meter and the system to a remarkable extent.
 
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*.
 
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
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.
 
Indication Of Negative Values On The Analog Scale
The measuring principle employed permits the measurement of the root-mean-square value (TRMS) of AC quantities and mixed quantities (AC and DC) regardless of the waveform.
 
Automatic Data Hold*
The DATA HOLD function makes it possible to hold the digitally displayed measured value. According to a patented method, 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.
 
Auto-ranging / 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.
 
Continuity Test
This permits testing for short circuit and open circuit. In addition to the display, a facility of sound signal is available.
 
Temperature Measurement
It is possible to use all models of RISH multi series, in direct connection of temperature sensor Pt 100 / Pt 1000. The meters automatically detects the type of sensors connected to it & displays directly measured temperature.
 
Signaling in the case of a blown fuse
The display FUSE points to a blown fuse.
 
Power economizing circuit
The meter disconnects automatically when the measured value remains unchanged for about 10 minutes and no operating control was operated during this time. The disconnection facility can be disabled.
 
Overload Warning
A sound signal indication violation of the overload limits.
 
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.
 
The top model Rish multi 18S features a 4 3/4 digit display (31 000 digits) as well as the following additional functions: Event counter, measurement of the duration of the event, time counter (stop watch), data compare, dB measurement, wide-range capacitance measurement.
