  • Page 4 ALIBRATION AND PERATION • When power is applied, display will read 1290 then a Pressure reading. At this point, be sure that no pressure is applied and that the transducer is at operating temperature. • Press the F key and the legend LO. OFF appears. Using the Up arrow key, advance the legend to LO.ON.
  • Page 5 0.52” LED display provides a precise, readable indication of the measured value. You can program the 1290 to display in engineering units up to a full scale value (fsv) of 99,900 with an accuracy of ± 0.1%. The span value, alarm set points and other constants are stored indefinitely in non-volatile memory.

  • Page 14 Fig. 5 Front Panel and Circuit Board Assembly 4.5.2 O UTPUT UMPER ETTINGS Output options are selected by the placement of jumpers on the upper circuit board. The choices available are: • Voltage or current loop output for analog retransmission. Jumper setups are shown in Figure 6. The default selection is a 4-20 mA current output, with alarm outputs normally closed.
  • Page 15 4.5.4 R EASSEMBLY To reassemble the Model 1290, follow the steps below. 1. Slide the front panel and printed circuit board assembly into the instrument case and press it in so that the printed circuit board contacts mate with th terminal block in the back of the case.
  • Page 16 The configuration/calibration mode is enabled by opening the Mode Selection Switch on the left side of the lower board (see Figure 7). A list of all configurable parameters starts below. When the unit is turned on in configuration/calibration mode, the display will show 1290 and then COnF .
  • Page 17 This value corresponds to the percentage of the Full Scale Value. NOTE: When using Dynisco transducers, the Shunt Calibration value should be set to 80.0 EXTERNAL CONTACT function The display shows E.C. (External Contact) followed by: nr to enable external contact for manual alarm reset, via rear terminals 7 and 8, or Ho to enable external contact for hold-on-value sampling.

  • Page 20 L2. ANALOG RETRANSMISSION SCALING: FULL SCALE VALUE The display alternately shows Ar. F.S.U. (Analog Retransmission Full Scale Value) and a numerical value. This parameter establishes the upper limit for the analog output; only the numerical value is shown during modification. Resolution and decimal point position are as selected for the readout value.

  • Page 21: Operating Mode

    PERATING In this mode the Model 1290 monitors the input signal, displays the measured value, and performs alarm functions. You can display high and low peak values, lock and unlock the keyboard, reset alarms, and perform transducer input calibration and alarm threshold settings. It is also possible to load default parameters.
  • Page 22 2. FULL SCALE TRANSDUCER CALIBRATION The display alternates between FU.S.C. and the value of full scale in engineering units. Press the key once. The display shows FU on . Press F to go to perform the full scale calibration. The indicator automatically returns to operating mode after 6 seconds if no changes are made. 3.

    1290 Strain Gage Input Indicator EFAULT ATA FOR ALIBRATION ARAMETERS Default calibration parameters are provided to allow the user to verify that the instrument is working properly. They are not normally used as the final calibration values. CAUTION: After default parameter loading, you should perform the proper indicator calibration procedure.
  • Page 26 Er 39 Error detected during EAROM write operation. This error may appear in operating mode when storing a new value in EAROM (for example, alarm threshold or transducer calibration). the new values will be enabled but they will be lost when the instrument is powered down. This error message disappears automatically after 10 seconds.
