ROUBLESHOOTING
This chapter describes how to maintain and troubleshoot the LDT-5500B Series
Temperature Controller. Included are sections covering calibration, disassembly,
and troubleshooting.
THE SERVICE PROCEDURES DESCRIBED IN THIS CHAPTER ARE FOR USE BY
QUALIFIED PERSONNEL. POTENTIALLY LETHAL VOLTAGES EXIST WITHIN THE

LDT-5500B SERIES TEMPERATURE CONTROLLER. TO AVOID ELECTRIC SHOCK, DO
NOT PERFORM ANY OF THE PROCEDURES DESCRIBED IN THIS CHAPTER UNLESS
YOU ARE QUALIFIED TO DO SO.


QUALIFIED SERVICE PERSONNEL ARE REQUIRED TO WEAR PROTECTIVE
EYEGLASSES AND ANTI-STATIC WRIST BANDS WHILE WORKING ON THE LDT-5500B
Series TEMPERATURE CONTROLLER CIRCUIT BOARDS.
HIGH VOLTAGES ARE PRESENT ON AND AROUND THE PRINTED CIRCUIT BOARDS OF
THE LDT-5500B SERIES TEMPERATURE CONTROLLER.
Calibration Overview
The LDT-5500B Series Temperature Controller should be calibrated every 12
months or whenever performance verification indicates that calibration is
necessary.
All calibrations can be done with the case closed. The instrument is calibrated by
changing the internally stored digital calibration constants.
