Error 61,
LOAD NOT GT LOAD
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 93.
Error 62,
SLAVE NAK
The channel’s microprocessor is responding to a message, but it did not acknowledge
it correctly. Restart the instrument.
Error 67,
LOADS NOT CLOSE
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.
Error 68,
CAN'T CALIBRATE
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
menu item is set to one of the Known-Load Calibration
settings, no calibration can take place. Either re-connect the original transducer or
use the SETUP menu to perform a calibration.
Error 70,
CAN'T DO GAIN
The channel’s EEPROM memory contains an input range setting which is beyond the
capabilities of the channel. Change the channel’s
CALIBRATION DATA
->
FULL SCALE MV/V
menu item to another setting.
Error 71,
SLAVE CHECKSUM
The channel’s microprocessor did not send a correct checksum to the instrument.
Restart the instrument.
Error 72,
CAN'T DO FILTER
The channel’s EEPROM memory contains a frequency response setting which is not
understood by the instrument. Change the channel’s
OPERATION
->
FREQ. RESPONSE
menu
item to another setting.
Error 73,
SLAVE NOT INIT
The channel’s microprocessor has not yet been initialized by the instrument. Restart
the instrument.
Error 74,
SLAVE BAD REPLY
The channel’s microprocessor replied with a message that was either not understood
or different than expected. Restart the instrument.
Error 75,
SLAVE NOT FOUND
The channel’s microprocessor did not respond. Restart the instrument.
Error 81,
OPERAND EXPECTED
The first step of a SensoCode program must be an Operand. The SensoCode pro-
gram loaded in the Mathematics Virtual channel is invalid.
Error 82,
BAD OPERAND
The SensoCode program loaded into a Mathematics Virtual channel contains a bad
operand.
Error 83,
BAD INSTRUCTION
The SensoCode program loaded into a Mathematics Virtual channel contains a bad
instruction.
Error 84,
BAD VALUE
A Mathematics Virtual channel has attempted to get a value from a channel not
installed in the instrument.
