Field Serviceable Repairs

Repairs are considered field serviceable if the repair will not alter the calibration or

proper operation of the instrument.

•

All probes designed to work with the thermometer are fully interchangeable.

•

All components in the Model 678 and Model 679 can be replaced without affecting

instrument operation or calibration. Some minor changes to the exact calibration

point will be caused by changing R8, and R13, but as long as the proper type and

tolerance resistors are used (0.1% and 0.05% as supplied by Welch Allyn), the

unit will remain within specifications.

•

Replacement of the LCD frame is somewhat difficult due to the need to assemble

it while under pressure to assure proper compression of the elastomeric

connector.

Note:

Do not glue the LCD frame to the display PCB if the frame latching pins are

broken. This will destroy the display. Replace with a new LCD frame.

Field Serviceable Parts
