Table 5-1 summarizes calibration error numbers, titles and descriptions for
the HP E1411 multimeter. Note that an error is returned if the adjustment
(calibration) standard used is outside the calibration range of the multimeter
(between [0.5 full scale and full scale]).
Table 5-1. HP E1411 Multimeter Calibration Errors
Title
No error has occurred since last time the error code was read.
The FIFO memory was still full at the time the new reading
was ready, or a new command was received while in the
middle of outputting a reading. TRIGGER ARM is disabled
and the multimeter waits for a new command.
An error occurred when computing a calibration constant,
probably due to an improper input or a defective Unit Under
Test (UUT). Calibration cycle aborted.
The non-volatile RAM contains a checksum error. The data is
assumed to be corrupted.
Calibration requested for an invalid combination of multimeter
range and function.
The target value for the calibration was outside the range of
(0.5 full scale to full scale).
No response from inguard (expected data and got nothing).
Timed out instead.
An error has occurred during a linearity calibration sequence.
Probably a hardware failure of the A/D inguard section.
The pacer is in use and the pacer rate is faster than the
maximum A/D conversion rate based on integration time,
autorange setting, autozero setting, and interrupts enabled.
A potentially damaging overload has been applied to the
multimeter terminals and the multimeter has disconnected
from the input. A new SET RANGE command is necessary to
restore normal operation. A damaging overload is defined as:
1. Applying > 40 volts Hl to LO or Hl to COMMON while in
manual range with RANGE
2. Applying > 40 volts between LO and COMMON under any
circumstances.
Description
8 volts.
