Error Codes
The transmitter has error codes that can be displayed on the serial line
using the ERRS command. See section Display the Currently Active
Errors on page 50.
Table 9 Error Codes
Error Code Cause
Ambient temperature error Ambient temperature out of operating
range (probably too hot).
Autocal error Transmitter unable to complete auto-
calibration after several attempts. Can
be caused by continuously changing
measurement environment, problem
with supply voltage, or transmitter
malfunction.
Voltage error Supplied operating voltage is too low
or high for reliable operation, or there
is a problem with voltage
measurement.
Voltage too low error Supplied operating voltage is too low
for reliable operation.
Voltage too low for mA output error Supplied operating voltage is too low
for reliable operation of the analog
current output.
Note: It is normal to receive this error
when using the MI70 indicator or the
USB serial interface cable, as they do
not provide a sufficient operating
voltage to operate the current output.
To avoid this error, connect a power
supply for the transmitter in
connector I before connecting the
MI70 indicator or USB cable. See
section Power Supply Requirements
on page 22.
T meas error Internal error, can be caused by
damage to the sensor.
F meas error Internal error, can be caused by
damage to the sensor.
Internal error Transmitter unable to function. Can be
caused by transmitter malfunction or
unsuitable measurement environment.
