to return to the ‘Test QIC’ menu.
6. Accuracy & Linearity Check mA output circuits
In the ‘Test QIC’ menu, set
mA output
to ‘Check’.
In the next menu the simulated mA values to mA1 and mA2 (at the same time) can be
selected, by setting
Command
to ‘Next value’.

During production test procedures the also the ripple at 12.0 mA is tested and the mA-value
at 22.0 mA, witha 600

resistor instead of the normal 300
Ω

Press Back button
to return to the ‘Test QIC’ menu.
-
Set
Quit test
to ‘Yes’
-
Press Home button
to return to normal operation.
Note:
if you do
not set
Quit test
to ‘Yes’, and return by only pressing the Home button, or
even by the Auto Return timer, the Normal operation will not operate properly !
7. Overall Accuracy Test
The overall accuracy test is executed in normal operation mode, but it requires a number of
settings to be modified. It is recommended that the current instrument settings are recorded
before this overall accuracy test is executed.
The required settings are (see IM how to change):
-
main parameter
= Conductivity
-
temp. element
= Pt1000
-
temperature
compensation (conductivity 1) = NaCl
-
mA1:
-
process parameter = conductivity
-
output – linear
-
0% value = 0 S/cm
-
100% value = 500
µ
S/cm
-
mA2:
-
process parameter = temperature
-
output – linear
-
0% value = 0

-
100% value = 100
