5.6 Self-Diagnosis
1 Press and hold Read and Cal simultaneously until the meter displays the full screen.
Each icon blinks one after the other. This way you may check whether all icons are correctly
shown. The next step is to check that the keys are functioning correctly. This requires user
interaction.
2 When blinks, five icons are displayed. Press the five keys in any order.
Each time you press a key an icon disappears from the screen.
3 Continue to press the other keys until all the icons have disappeared.
When the self-diagnosis has been completed successfully, PAS appears. If self-diagnosis fails,
error message Err 1 appears (see "Error Messages (page 13)").
Note
You have to finish pressing all five keys within two minutes, otherwise Err 1 appears and you will have
to repeat the procedure.
