THERMAL SENSITIVITY TESTER, NTE-2A 1.0 GENERAL DESCRIPTION The NTE-2A Controller is a sophisticated testing instrument which provides a means of accurately measuring a subject’s ability to distinguish small differences in temperature. The thermal probe is driven by a thermoelectric (Peltier effect) module. These modules have the unique ability to provide temperature stimuli above and below room temperature.

2.0 INITIAL INSTALLATION 2.1 EQUIPMENT SUPPLIED After unpacking the instruments, check that all parts of the system are present. The boxes should contain: 2.1 1 Controller NTE-2A with AC line cord 1 Thermal Probe 1 Water Pump and Tank Unit, PTU-110A, with 2 water tubes and AC line cord 1 Operating Manual WATER PUMP AND TANK UNIT Unscrew cap. Fill reservoir with two and a half gallons of distilled water.

2.3 ATTACHING THE LINE CORD BEFORE CONNECTING CONTROLLER TO AC POWER SUPPLY CHECK THE SETTING OF THE VOLTAGE SELECTOR MODULE. This module is on the back panel, bottom left. There are four settings. Be sure selector is set for your power requirements. A red indicator should be visible beside the correct voltage in the list printed on the fuse cover. If the red indicator does not mark the correct voltage, the card inside the fuse case must be pulled out and reinserted with the proper orientation.

Insert the water tubes from the probe into WATER INLET and OUTLET connectors on the front panel of the controller. These tubes are interchangeable -- direction of flow is not important. Insert polarized electrical connector from stage into POWER OUTPUT socket on front of the controller. Twist the locking nut in a clockwise direction to lock connector to the controller. Insert blue thermocouple connector into socket labelled SENSOR B - STAGE. Switch SENSOR INPUT to B position.

Connect AC line cord from the controller to an AC outlet and turn ON. A buzzing noise from water pump indicates that pump is running. Remove tank cap and check that water is flowing. The power indicator light on the controller and tank unit will light. IF EITHER LAMP FAILS TO LIGHT, SWITCH OFF and check fuses. 3.0 OPERATING INSTRUCTIONS 3.1 ADJUSTMENT OF BASE TEMPERATURE OF CONTROLLER All parts of the system must be connected and turned on.
