8. Diagnostics
8.1. Error Table
In the Diagnostics menu, select Error table (1). If self-
diagnostics has not detected any errors, the display
shows "NO ERRORS". If self-diagnostics has detected
errors, the first line of the display shos the timestamp
when the error state began. The second row shows
the timestamp when the error state ended. The third
row shows the error type.
If the error state is still in effect, the ending timestamp
is shown as '--'. The message 'Shutdown' in the place
of the error state end time notifies, that the error state
was on when the power was shut down. If the error
state is still on when the power is switced on next time,
the error is reported as a new error. The Error table
shows the 10 most recent errors.

8.2. Diagnostics Values
In the Diagnostics menu, select Diag. Values (2). The
following display appears:
C a b t e m p = 4 0 . 6 C
M l e v = 1 2 1 m V
R l e v = 2 1 4 . 4 m V
M s t a b = 9 . 8
R s t a b = 2 . 1
E l d r i f t = - 2 . 4
V C O d r i f t = 3 . 2
P r o c t e m p = 4 2 . 0 C
The display shows values for the following diag-
nostics measurements:
Cab temp: Sensor electronics temperature.
Proc temp: Process temperature.
Mlev: Measurement signal level.
Rlev: Reference channel signal level.
Mstab: Measurement channel signal stability.
Rstab: Reference channel signal stability.
El drift: Reference channel drift.
VCO drift: Signal generator drift.
Usage of this data for maintenance purposes is ex-
plained in more detail in Chapter 10, "Troubleshooting
and Maintenance".
8.3. Diagnostics Limits
In the Diagnostics menu, select Diag. Limits (3). The
following display appears:
Ctmp max = 90 /OFF
Ptmp max = 1000 /ON
Ptmp min = 0.0 /ON
M.Lev min = 10.0 /ON
R.Lev min = 100.0/ON
Mstab max = 20.0 /ON
Rstab max = 2.0 /ON
Eldr abs = 80.0 /ON
VCOdr abs = 50.0 /ON
The display shows the error limit for each diagnostics
measurement as well as its effect on the current signal
(ON/OFF). If necessary, you can change these as fol-
lows: press the EDIT button and then enter a new error
limit, or use the up arrow and down arrow buttons to
change the ON/OFF setting.
Even if the effect of the limit on the current signal is
blocked by an OFF setting, an error message still ap-
pears on the main display status line and error data is
entered into the error table.
