GA MMA-M instrument designed to measure (weight, load, pressure, displacement, or DC current using external shunts) accepts transducers like Load-Cell, Pressure Transmitter, Linear Potentiometers, Shunts. Etc... Two scaling ways, manual or teach, levels of filter selectable by key as well as last digit resolution make easy to adapt the instrument to any input signal. Setpoints with possibility of Latch, Delay or Hysteresis, working related to Peak, Valley or Peak-Peak value. The serial communication allows, using a especial function, transmitting at 200 readings per second, during all time this special function is activated. A s standard has four different excitation voltages to supply the transducers: 10 V, 5 V, 2.2 V y 24 V.

GAMMA-M OPTIONS FRONT PANEL FUNCTIONS Serial communication protocols: standard, ISO1745 and MODBUS RTU. STANDARD FUNCTIONS TARE The tare operation is accomplished by a push of the TARE key on the front panel or by applying a low level signal to the corresponding logic input at the CN2 connector. The tare memory is cleared to zero by a combination of the RESET and TARE keys (also at the CN2 connector). PEAK & VALLEY, PEAK-PEAK The instrument detects and memorizes the max and min values reached for the variable after the last reset (peak and valley, peak-peak). To display the peak value, press...

GAMMA-M Programmable logic functions (CN2) The rear connector CN2 provides 4 user programmable optocoupled inputs NPN or PNP that can be operated from external contacts or logic levels supplied by an electronic system. Four different functions may be then added to the functions available from the front-panel keys. Each function is associated to one of the CN2 connector pins ( PIN1, PIN2, PIN3, PIN4 and PIN 5) referred to PIN 3. Each PIN can be assigned one of the 31 functions listed on the following table.
