1290 Strain Gage Input Indicator 25
6.3 DEFAULT DATA FOR CALIBRATION PARAMETERS
Default calibration parameters are provided to allow the user to verify that the instrument is working
properly. They are not normally used as the final calibration values.
CAUTION: After default parameter loading, you should perform the proper indicator calibration
procedure.
7. ERROR MESSAGES
Diagnostics are performed at instrument startup and during normal mode operation. If a fault
condition is detected, the display will show the message
Er
followed by an error code. The following
is a list of possible errors in numerical order.
Er 1
The alarm threshold values or transducer calibration (tare or zero) are out of limits or their values in
memory are incorrect. The error may appear at instrument startup in operating mode.
After 3 seconds, the instrument will reset. Simultaneously press ▼ and ▲ to load default data. Then
load the desired threshold values and recalibrate the transducer.
Er 6
This error message appears during tare or zero transducer calibration if input value is greater than
±25% of full scale calibration. The same error message appears during full scale calibration if the
stored zero calibration value is greater than ±25% of the new full scale calibration. In both cases the
stored calibration value is not changed. This error message disappears automatically after 2 seconds.
Er 7
This error message appears during zero or full scale transducer calibration if a fault condition (hold-
on-value/overrange/underrange/input open) is found on an input signal or if the span value is too
large (>55 mV) or too small (<2.8 mV). In both cases the stored calibration value is not changed.
This error message disappears automatically after 2 seconds.
Er 38
Error detected during EAROM read operation. This error may appear at instrument startup in
operating mode. This error message disappears automatically after 3 seconds, and the instrument
resets. If the error persists, return the instrument to your supplier.
If this error appears during configuration/calibration, press F or R to restart the procedure and then
repeat operations. If the error persists, return the instrument to your supplier.
