Calibration
Errors
Table 5-1 summarizes calibration error numbers, titles and descriptions for
the 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. E1411 Multimeter Calibration Errors
Error Title Description Code*
0 No Error No error has occurred since last time the error code was read.
4 Reading
Overrun
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.
U
6 Calibration
Error
An error occurred when computing a calibration constant, probably
due to an improper input or a defective Unit Under Test (UUT).
Calibration cycle aborted.
U/H
7 Checksum
Error
The non-volatile RAM contains a checksum error. The data is
assumed to be corrupted.
H
8 Invalid
CAL
Request
Calibration requested for an invalid combination of multimeter range
and function.
U
9Bad CAL
Target
The target value for the calibration was outside the range of ±(0.5 full
scale to full scale).
U
11 No
Inguard
Response
No response from inguard (expected data and got nothing). Timed out
instead.
H
13 Linearity
CAL Error
An error has occurred during a linearity calibration sequence. Probably
a hardware failure of the A/D inguard section.
H
14 Pacer
Overrun
Error
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.
U
15 Input
Overload
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 ≤ 8 volts.
2. Applying >±40 volts between LO and COMMON under any
circumstances.
U
* U = improper operation, H = hardware failure
