maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to ensure that liquids are not permitted

    Maintenance and Repair It is not recommended that the customer attempt to repair model 482C27 in the field. Should trouble occur, contact the factory for assistance. If the unit becomes dusty and dirty, it may be wiped off with a soft cloth.
  • Page 16: Submenu Format And Command Selections

    1) Gain Functionality – Includes five menu selections The following menu options all pertain to how the gain functionality operates in the 482C27. Gain Type (GType on front panel): Allows the user to choose how the gain of each channel can be set. The selections in the submenu are Gain and Normalize (Gain is the factory default setting).
  • Page 17 0010.0 The 482C27 has the ability to automatically normalize the output sensitivity of each channel based on the sensitivity of the sensor (SENS), the full scale value of the input (FSIN) in engineering units (g’s for example) and the full scale output (FSOT) of the amplifier expressed in volts (this is the output that a signal at an FSIN level will produce).
  • Page 18 See section 1-4.2b. 3) Input Filter (FLTi on front panel): A screen stating ‘This Option is Not Installed’ will appear. The 482C27 does not come standard with an input filter, but the option is available. Contact the factory for more information.
  • Page 19 02 mA The 482C27 will turn off the current excitation signal if the unit is not in ICP® input mode and will not allow it to be set while unless it is in ICP® mode.

  • Page 20 10.00 The 482C27 will turn off the voltage excitation signal if the unit is in ICP® or voltage input mode and will not allow it to be set while in those modes. If a channel is selected from the EXCv menu that is inappropriate then NA will appear as shown below in place of the voltage and polarity settings.
  • Page 21 8) Auto Zero/ Auto Balance (ZERO on front panel): 482C27 includes an auto zero function for automatically zeroing channel outputs for any channel in DC coupling mode (zeroing works for any sensor input type). The auto balance function works for channels that are set to differential voltage, bridge (quarter, full, half), RSE and NRSE input modes ONLY (when DC coupling is enabled).

    2 to 20 mA (current can be fixed or variable depending on the signal conditioner model). Sensor excitation occurs as the constant current of all channels are set. Model 482C27 allows the constant current to be adjusted between 1 and 20 mA to provide the required excitation for most applications. Special situations, such as driving extra-long cables (more than 1000 ft) with high frequency or fast rise time pulses, may require increasing the drive current to 12 mA or higher.
  • Page 28: Input Protection

    Input Fault Detection Model 482C27 monitors two input fault conditions, “short” and “open,” which indicate problems with sensor input and is displayed through the front panel LEDs. Either case implies that the sensor is NOT functioning properly. An input is shorted when it has a ground path for the sensor excitation and open when the sensor fails to draw the excitation.
  • Page 29: Auto Scaling And Overload Detection

    3-6.1 Auto Scale To avoid overload, model 482C27 features auto scaling for automatic gain adjustment (appears as ARNG on front panel display). It first sets maximum gain on all channels, then decreases the gain setting of any channel on which an overload has occurred.
