2.6 General Operating Procedures

The following sections present some guidelines for operation, as well as some common operating procedures.

2.6.1 Warm-Up and Environmental Considerations

Operate the LDT-5525 Temperature Controller at an ambient temperature in the range of 0 to +40 °C. Storage
temperatures should be in the range of -40 to +70 °C. To achieve rated accuracy, let the LDT-5525 Temperature
Controller warm up for about 1 hour before use.

2.6.2 Temperature Mode Operation

You can operate the LDT-5525 Temperature Controller in several modes, constant current (I TE), constant thermistor
resistance (R), or constant temperature (T). This example is for constant temperature (T) mode.
a. Plug the LDT-5525 Temperature Controller into an AC power source supplying the correct voltage and
frequency for your unit (refer to the back panel for the correct ratings).
b. Turn on the LDT-5525 Temperature Controller. The OUTPUT stage will be off at power-up and the unit will
automatically configure its parameters to the state which existed when the power was last shut off.
c. Press the ENBL switch in the ADJUST section of the front panel so that the indicator is lit (adjustment
enabled). Press the MODE switch until the T mode is selected.
d. Check the setting of the SENSOR SELECT switch for the desired operation. The sensor code will be
displayed for two seconds during the power-up sequence (see Section 2.3).
