1.Introduction
Final testing begins with a visual inspection of the unit to ensure that all the relevant parts
are present and correctly fitted. After switching on the power to the unit, 5 minutes should
be allowed for warm-up, and to stabilise the instrument completely before taking
measurements.
The Device ID. and Sofware revision are shown on the display after pressing the Zoom
button and two times the Enter button .
2.Safety tests
During the production test procedures, the insulation is tested between terminal 3, the
supply earth, and power terminals 1 and 2. The test used applies the following criteria:
AC instruments - 2.1 kV DC, <1 mA, for >1 min.
DC instruments - 0.7 kV DC, <1 mA, for >1 min.
The outputs are also tested for isolation from earth
≥
9.5 MW.
3. Functional tests
During the production test procedures, the following tests are executed as functional test:
●
Visual check during startup
●
Check for the correct language
●
Voltage and current check
●
Contact relay operation check
●
Input contact operation check
The checkbox ‘Functional test’ on the QIC form is used for the result of these checks.
The
Contact Relay operation check
can also be executed separately:
-
Press Setup button
-
Go to
Commissioning
-
Go to
Advanced setup
-
Go to
Test QIC
-
Set
Key
to ‘Factory Mode’
-
In the ‘Test QIC’ menu, set
Contacts
to ‘Check’
-
In the next menu the simulated value to S1 and S2 (at the same time) is set to On or
Off, by setting
Command
to ‘Next value’.
-
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 !
Communication test HART
During the production test procedures, the communication via the HART protocol is tested
using specialized equipment.
Date / time test
During the production test procedures, the clock is set and a check is performed to verify
that it is running.
The actual date and time of the instrument is shown on the display after pressing the Zoom
button once.
