Constant Temperature Mode Operation

1. Plug the LDC-3706 Instrument into an appropriate AC power source supplying the correct
mains voltage and frequency for the instrument (refer to the rear panel for the correct ratings)

on the TEC side display (LEFT) and cycle through the available display parameters by
pressing the LEFT (left) and RIGHT (left) display buttons
