Page 4: Description And Specifications
DESCRIPTION The Model 9834 is an enhanced performance, microprocessor-based digital indicator capable of interfacing to high-level voltage ( 5 or 10VDC) or current (4-20mA) output transducers. A 16-bit analog-to-digital converter accurately digitizes the input signal. A 12VDC@90mA, short circuit protected, transducer excitation supply is also provided. Self-calibrating 10VDC and 4-20mA analog output signals are standard with this instrument. -

S1 S2 S3 Mode Selection Switch (S1) S1 is used to cycle through the various programmable functions of the 9834. The sequence is as follows. The designators, in ( ), identify text that will be displayed. The settable values are shown in { }... - Page 10 SWITCH DEFINITIONS (CONT) Increment or Cal Switch (S3) This switch serves two functions, depending on the present status of S1. If the instrument is in the Mode Selection sequence, this switch will increment the flashing digit. If the instrument is in its operating mode, S3 becomes an AUTO CAL switch. CAUTION: If CAL function has been activated, depressing this switch will cause the instrument to recalibrate its full scale reading.
- Page 11 FUNCTION DEFINITIONS Filter Value (FILtEr) {00 to 99} The 9830 uses a filter based on exponential smoothing, a digital averaging technique where the recent conversions are given more weight than the older conversions. The weighting factor is the value of (FILtEr). The formula for the exponential filter is: = (1-F)C where S the new smoothed value...

Page 17: Calibration Instructions
CALIBRATION INSTRUCTIONS The Interface Model 9834 can be calibrated using (2) different methods. 1. The first method uses actual or simulated ZERO and FULL SCALE (FS) inputs. Actual inputs may come from a transducer loaded with calibrated weights. Simulated inputs may come from a voltage calibrator. - Page 18 CALIBRATION INSTRUCTIONS (CONT) 9. Enable the CAL switch. Reference PROGRAM INSTRUCTIONS Step 1 on Page 10 to enable the CAL switch. Note: Enabling the CAL switch allows only one attempt at calibrating the instrument. If calibration is not successful, repeat the whole calibration procedure.
- Page 19 CALIBRATION INSTRUCTIONS (CONT) CALIBRATION USING THE REF SWITCH 1. Attach a calibration adaptor to J1. 2. Apply power to the instrument. 3. The TARE and CAL LED's on the front panel should be illuminated 4. Depress the TARE (S2) switch once. The TARE LED should extinquish. The instrument should now display the UNTARED reading.

Page 20: Serial Rs232 Communications
No Parity Bit; One Stop Bit Transmissions from the Model 9834 are controlled by sending XOFF (ASCII code decimal 19, DC3) to suspend character transmission and XON (ASCII code decimal 17, DC1) to start transmission. All transmissions to the Model 9830, including XON and XOFF, must terminate with a CR (hex OD) and only a CR. - Page 21 SERIAL RS232 COMMUNICATIONS (CONT) Examples of Transmitted Data Byte Value in Hex Value in Decimal No SP Exceeded Instantaneous Display Displayed Number = -10.45 Decimal = xxx.xx Byte Value in Hex Value in Decimal SP 2 Exceeded Valley Display Displayed Number = -993.78 Decimal = xxx.xx Commands The XON and XOFF commands only affect the transmission of data from the selected...
