Special Features Automatic terminal blocking system (ABS) Min/Max value storage Indication of negative values on the analog scale Overload warning
Application Gamma is the Analog Digital Multimeter which measures VAC, VDC, VAC+DC,Frequency, ma DC, ma (AC+DC), Resistance, continuity, Diode, Farad, AC current measurement. Product Features Automatic Terminal Blocking System (ABS) Interface And Software MIN / MAX Value Storage Indication Of Negative Values On The Analog Scale Indication Of Negative Values On The Analog Scale Automatic Data Hold* Autoranging / Manual Range Selection 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. In addition to the display of the actual measured value, the minimum or maximum value can constantly be updated and stored. 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. 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. 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. 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/MAIN push button. Continuity Test Temperature Measurement Signalling in the case of a blown fuse Power economizing circuit This permits testing for short circuit and open circuit. In addition to the display, a facility of sound signal is available. It is possible to use all models of Gamma, in direct connection of temperature sensor Pt / Pt. The meters automatically detects the type of sensors connected to it & displays directly measured temperature. The display FUSE points to a blown fuse. The meter disconnects automatically when the measured value remains unchanged for about minutes and no operating control was operated during this time. The disconnection facility can be disabled. Overload A sound signal indication violation of the Warning overload limits. Protective holster for rough duty Top model Gamma Calibration The top model Gamma features a 4 3/4 digit display (3 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. www.sifamtinsley.com Page of 8 Version No.GA /5/
