Error Messages
CAL Err
- This indicates that one of the calibration points has caused an overrange error in the
analog to digital converter. Check the input link settings against the live input then try calibration again.
SPAN ERR
- This indicates that the calibration points entered were too close together. Try calibrate
again with the points further apart. The calibration points should be at least 10% of full scale apart,
ideally as close to 100% of full scale as possible.
ZERO RNGE Err
- This indicates that an attempt to zero or preset a value on the display has failed
due to the
ZERO RNGE
function value being exceeded. Check the
ZERO RNGE
function setting, if this
is set at the required figure and the display value seems to be within the zero range limits then it could
be that previous zero operations have caused the limit to be exceeded.
"
----
" - This display indicates that the actual input is higher than the input link settings e.g. a 10V
input being used when the link settings are for a 0 to 1V input. Check the link settings and the live input
value.
"
-or-
" - This display indicates an overrange reading. This could be due to the instrument not being
able to display the number because it is too large e.g. above
9999
on a 4 digit display. Alternatively it
could mean that the
Lo
or
HIGH dISP
limit value has been exceeded and the instrument is showing
a warning message.
Value on display flashing
- this means that the
Lo
or
HIGH dISP
limit value has been exceeded
and the instrument is showing a warning message.
Returning to normal measure mode
When the calibration has been completed it is advisable to return the instrument to the normal mode
(where calibration functions cannot be tampered with).To return to normal mode, turn off power to the
instrument, wait a few seconds and then restore power.
