Fig. 12.8. Diagnostics menu.
12.B.4. Diagnostics
The DIAGNOSTICS menu is shown in Fig. 12.8.
The first two functions (temperature & chemicals
compensation) are described in section 12.C of this
manual. The other functions of the menu are described
below.
Loop test
Each of the MCAi sensor’s current outputs can be set to
a desired value to test the current loop.
Device Status
This function lists all error types of the self-diagnostics
and indicates whether an error is on or not (ON/OFF).
Device values
From this menu you can read the following measured
values:
• Mlev = measurement signal level (u),
• Rlev = reference signal level (V),
• Meas stab = stability of measurement signal,
• Ref stab = stability of reference signal,
• Chem comp = chemicals compensation value (%).
Sample History
This table contains the measured values of the latest 30
samples, identified with running numbers (1–30). Type
a sample number and press E
NTER to display the sample
date and time and the measured values. The latest
sample is always no. 1.
Calibration History
A table where changes made to the calibration are
stored. The changes are identified with running num-
bers 1–30. Type a number and press E
NTER to display
data of the selected change: date, sample date, temper-
ature, laboratory consistency, MCAi consistency, and
ash content. Change number 1 is always the latest
change.
Master Reset
This command performs Master Reset to the device. It
is used in connection with start-up.
Cable Test
This function can be used to measure the attenuation of
the measurement channel in dB. The function is used
when locating a fault by using a simulation cable. For
more information see section 10.C of this manual.
