Comment: the status you have selected here remains
unchanged as long as you exit the menu, and the
instrument starts measuring.
10. You can exit from the display test by pressing the
MENU button. You see the blinking

mnemonic.
Current transmitter test
11. If you want to perform a test of the current transmitter,
use the ▲ buton to switch from the text

to the text

(its meaning is: analogue output test.).
12. Press the ENTER button.
13. Now this is visible on the display:

. Now the
apparatus sets the loop current to 4 mA (irrelevant to the
measured temperature value, as this is a test function).
14. By using the
▲ button, you can set any current values
between 4 mA and 20 mA, in 1 mA steps.
15. By pressing the
► button again, you may select from
among the following operating modes:
•
4 mA
•
12 mA
•
20 mA
•
Stepping the current automatically (fast):
It decreases the current value from 20 mA to 4 mA (in 1
mA steps), then increases it from 4 mA to 20 mA (in 1-mA
steps), then decreases again, and so on. A complete
sequence of stepping up and down takes 1.6 seconds.
•
Stepping the current automatically (slow)
The same like the previous mode, but in this case the
apparatus waits for 5 seconds between each steps.
Exit from the menu item 1. Press the MENU button, to exit from the Tests menu
item, and you see this:

.
(2. If you want to return to the tests, go on from point 3 of
the Sequence of operations .)
(3. If you don’t want to exit the menu because you want to
perform further settings, you can select the desired menu
items by pressing the
▲ button.)
