OPERAND EXPECTED
A load applied during a known-load calibration was not greater than a previously
applied load. To insure both correct operation of the transducer and application of the
load, the instrument expects the voltage applied at each known-load point to be
increasing. For example, the load applied at Known-Load Point 2/2 must cause the
transducer to produce a more positive voltage than at Known-Load Point 1/2.
If you are calibrating with a AC-AC LVDT Input channel, make certain that you have
followed the procedure described in "Electrical Null and Transducer Mounting" on
page 87.
The channel's microprocessor is responding to a message, but it did not acknowledge
it correctly. Restart the instrument.
During a 5-Point Known-Load calibration, you would typically apply loads at 0%, 25%,
50%, 75% and 100% of the transducer's full-scale and optionally calibrate the return
points of 75%, 50%, 25% and 0%. The instrument makes sure that transducer read-
ings taken during the second application of the load are close to the readings taken
during the first application of the load. This insures both correct operation of the trans-
ducer and application of the loads.
The instrument has detected that the transducer presently connected to the channel is
different than the transducer the channel was last calibrated with. Ordinarily, the
instrument would perform a Shunt Calibration or mV/V Calibration. However, since
the channel's
CALIBRATION TYPE
settings, no calibration can take place. Either re-connect the original transducer, use
the SETUP menu to perform a calibration or use the SETUP menu to change the cali-
bration type.
The channel's EEPROM memory contains an input range setting which is beyond the
capabilities of the channel. Change the channel's
menu item to another setting.
The channel's microprocessor did not send a correct checksum to the instrument.
Restart the instrument.
The channel's EEPROM memory contains a frequency response setting which is not
understood by the instrument. Change the channel's
item to another setting.
The channel's microprocessor has not yet been initialized by the instrument. Restart
the instrument.
The channel's microprocessor replied with a message that was either not understood
or different than expected. Restart the instrument.
The channel's microprocessor did not respond. Restart the instrument.
The amplifer circuit's self test has failed. Check the wiring and re-start the instrument.
The setting of Jumper J23 on the Main Circuit Board (see Figure 10-4, "Location of
Shunt Cal Application Jumpers," on page 54) is incorrect. This jumper should be
installed on Strain-Gage Input channels when the setting of the
item is less than 5.5 mV/V. Otherwise, this jumper should be removed.
The first step of a SensoCode program must be an Operand. The SensoCode pro-
gram loaded in the Mathematics Virtual channel is invalid.
