Meaning
The test fixture lid is open during an auto-sequence program in which
the output voltage may exceed +42V. Press CONT to perform the
next step of the auto- sequence program.
Data Errors
Depending on the number of channels used in the measurement, up to
six 2-digit numbers are displayed, in the format shown below,
whenever the measurement cannot be performed correctly.
Error DXX XX XX XX XX XX
Here, XX is a 2-digit number which represents channel status. The
left-to-right order in which the 2-digit error codes appear corresponds
to the order in which the channels are assigned on the MEAS/DISP
MODE SETUP page. Also, the number of 2-digit error codes that
appear is identical to the number of channels used in the
measurement.
The left digit of XX is hexadecimal and must be
converted into a 4-digit binary number, as described below. The right
digit is decimal and requires no conversion. Also, zero means no error.
