Page 17: Storing And Recalling Values
3.10 Storing and Recalling Values In source mode the 1090 is able to store and recall up to ten output values. The values may be stored in locations 0 to 9. They can then be recalled manually or automatically. Used in conjunction with the ‘Auto Step’ function the unit can be programmed to output the stored values in sequence pausing at each value. - Page 18 3.10.2 Recalling Values Note: The 1090 stores numeric values, and not the units. Therefore, the correct units i.e. µV, mV etc. must be selected before the recall is done. To recall the stored values the unit must be in ’SOURCE’ mode.

CJ sense point in degrees C. 7) Pt100 Only perform this task if the mA/pt100 board is fitted. Connect a 300.0Ω precision resistor across the output terminals Press ENTER. The 1090 will then restart. 1090 Process Calibrator Page 32 of 35... - Page 33 The PRT/Current board has calibration adjustments on-board for current source and measure and can be supplied ready-calibrated for retrofitting in the field. When a 1090 unit is initially factory calibrated, it is necessary to fit a calibrated PRT/Current option board so that step 8 can be completed (this calibrates for the initial accuracy of the on-board voltage reference).
