This manual provides technical assistance for calibrating, diagnosing, and servic-
ing the Welch Allyn MICROTYMP 2 handle and Printer/Charger.
The MicroTymp 2 and or Printer Charger will be returned to the Technical Ser-
vice Department for either Recalibration (handle only) or for diagnosis and repair. For
Printer Charger tests, refer to current factory approved diagnostic tests. Once the fault
has been determined, refer to the Manual chapters I and J for the appropriate Removal
and Replacement sequence. Re-test the Printer Charger after the repair is completed.
Similarly, when servicing the MicroTymp 2 handle, refer to the most recent troubleshoot-
ing guide and Calvin Users guide. Once the failed component has been identified, refer
to the Manual chapters B through H for the appropriate Removal and Replacement
sequence. Re-test (re-calibrate) the handle once the repair has been completed.
The repair ‘TASK’ procedures (R & R .. Removal and Replacement) are written
to provide quick and easy reference for different experience levels of repair technician.
Required specifications and materials are listed at each step where applicable. For
example:
Instructions will start off with a “TASK, TO DO.” For example, B. 3. “Unplug Flex
Circuit” statement. This will be followed by a “TECHNIQUE, HOW TO DO” statement.
Follow these steps to preform the task.— “Grasp pump assembly flex circuit with pin
straightening pliers.”
This manual is written in a style useful for training and or translation. Set up
