Error Information

"Module Calibration
Lost"
During the start-up program initialization,
if the instrument can’t read the
calibration data from EEPROM, the
system will prompt an error.
EEPROM data is stored unsuccessfully.
While using the dual-range instrument,
you can’t turn the output on in 1s after
switching the range, otherwise the system
will prompt an error.
The odd and even parity of RS-232
communication is wrong.
"Front panel buffer
overrun"
The communication buffer is overflow
while using serial port.
The communication is overtime while
using serial port.
"CAL password is
incorrect"
While sending calibration command, if the
password is wrong and you can’t enter
the calibration mode, the system will
prompt an error. For example, for model
IT6831A, the correct calibration
command is CALibrate:SECure
0,”6831”, if you send CALibrate:SECure
0,”6811”, the system will prompt an
error.
If you haven’t switched into calibration
mode, sending related calibration
command will cause an error. For
example, if you haven’t switched into
calibration mode, sending
CALibrate:CURRent:LEVel P1 command
will cause an error.
"readback cal are
incorrect"
If you don’t calibrate the instrument
according to the function requirement, the
system will prompt an error. For example,
while calibrating one current point, the
setting current value is over the maximum
range, an error will occur.
"programming cal are
incorrect"
If you don’t calibrate the instrument
according to the function requirement, the
system will prompt an error. For example,
if you don’t send CALibrate:CURRent 0.1
after sending CALibrate:CURRent:LEVel
P1, then send CALibrate:CURRent:LEVel
P2 directly, an error will occur.
