Front Panel

The 5412 front panel is shown in Figure 2.1. Each of the front panel features is
described below..

AC Power-Up Sequence

With the LDT-5412 connected to an AC power source, pressing the POWER
off/on switch will supply power to the instrument and start the power-up sequence.

DISPLAY MODE Selection

The DISPLAY MODE select switch allows the user to select between the three
display modes. SET R mode is used to set the desired resistance of the
thermistor, and thereby set the temperature. ACTUAL R mode is used to read the
actual resistance of the thermistor, and thereby determine the actual temperature.
TE CURRENT mode sets the display to read the output current going to the TE
module. In this mode, the actual TE current can be read, but the LIMIT TE current
cannot be read on the display.

Current LIMIT Adjustment

The current LIMIT knob allows the user to set the upper limit of the output current.
The user may adjust the output current from zero (LIMIT knob fully counter-
clockwise CCW) to 2 Amps (LIMIT knob fully clockwise CW). This LIMIT knob is
recessed to prevent accidental readjustment of the output current during
operation.
