Chapter 17 Error Messages

17.1 Overview

If the instrument detects an error during the RUN, INITIALIZE, or
SETUP modes, it stops operation and enters its ERROR mode as
described in "Operating Modes" on page 6.

Description
A Mathematics Virtual channel has attempted to divide by zero.
A Mathematics Virtual channel has attempted to take the square root of a negative num-
ber.
A Mathematics Virtual channel has attempted to take the logarithm of either zero or a
negative number.
The internal +15 Vdc power supply is generating a voltage that is too high.
The internal +15 Vdc power supply is generating a voltage that is too low. Check the wir-
ing between the instrument and the transducer or amplifier.
The internal -15 Vdc power supply is generating a voltage that is too high (more positive).
Check the wiring between the instrument and the transducer or amplifier.
The internal -15 Vdc power supply is generating a voltage that is too low (more negative).
An invalid channel number has been encountered by the instrument. Restart the instru-
ment. If this error persists, contact our Service department with the information found in
the SYSTEM MENU -> SOFTWARE REV. menu item.
The instrument's software stack has overflowed. Restart the instrument. If this error per-
sists, contact our Service department with the information found in the SYSTEM MENU ->
SOFTWARE REV. menu item.
The instrument has not been programmed to understand the type of channel. Contact our
Service department with the information found in the SYSTEM MENU -> SOFTWARE REV. menu
item.
The full-scale value of the transducer cannot be rendered on the display with the selected
DISPLAY SETUP menu settings. Change the DISPLAY SETUP menu settings to better match
the transducer's capacity.
A checksum error occurred while reading a Signature Module's read-only-memory. Check
the wiring and restart the instrument. This error may occur with very long cable lengths.
A checksum failure occurred reading data from a Signature Module. Check the wiring.
This error may be caused by a faulty Signature Module.
No Signature Module was detected during UPDATE SIG.MOD. or DEFAULT SIG.MOD. Check
wiring.
The channel's EEPROM could not be detected during a write operation. Check that the
channel's address jumpers are set properly so that each card has an unique address.
The channel's EEPROM could not be detected during a read operation. Check that the
channel's address jumpers are set properly.
A verification failure occurred during a write operation to the channel's EEPROM. Restart
the instrument.
The channel's EEPROM could not be detected during an erase operation. Check that the
channel's address jumpers are set properly.
The channel does not appear to have been installed properly. This occurs if you swap
Input or Output boards without using SYSTEM MENU -> INSTALL CHANNEL to format the chan-
nel's EEPROM.

Wiring/electrical connection problems
Misplaced address jumpers when installing or removing
channel circuit boards
Swapping channel circuit boards between instruments
Incorrect calibration of the transducer to the instrument
