

Type K: connector the positive lead to #4 and the negative lead to #5.



PT1000 RTD: connect sensor leads to #4 and #5. No polarity.



NTC 50Kohm thermistor: connect sensor leads to #4 and #5. No polarity.



PT100 RTD: connect two wires of the same color to #4 and #5; connect the other lead

to #6.

The input sensor type on the controller, parameter "Sn" (Sn), must be set to match the

actual sensor type that is connected. By factory default, the controller is set to ready type K

thermocouple (K). Please see section 8.2 for details.

5.3. Control Output

The output signal from this controller is a 12VDC signal, which can be used to drive solid‐state

relays. The output status is indicated by the green OUT LED on the front panel.

6. Changing the Set Value

The default Set Value (SV) is 100°F. To change the Set Value:

1. Turn the knob and a flashing dot will appear on the lower right corner of the SV window.

2. Turn the knob to clockwise to increase the SV; turn the know counter‐clockwise to decrease

the SV. Once get to the desired SV, press down the knob to save the new value. Otherwise, the

old SV will be restored.

3. Once the new SV is confirmed, the dot in the lower right corner will go away.

4. The SV can be changed continuously between the temperature value and the power

percentage value. Please see the next section for details.

5. If the SV is set to a percentage value, the lower window will show letter "P" on the left

window. The A‐M LED diode turns on to indicate that the controller is working in manual

control mode. (Figure 3)

7. Switching between Auto Mode and Manual Mode

One of the most convenient features in DSPR‐5 is that the SV can be changed continuously between a

temperature value (0°F to 932°F) and a power percentage value (0% to 100%), and the corresponding

control mode between changed as well between the Auto Control Mode and the Manual Control

Mode.

Auto Control Mode

When the SV is a temperature value, the controller works in automatic control mode, which means the

controller will automatically adjust the output power to bring the temperature to the target value. The

lower window will just show a number without any letter. The yellow A‐M indicator should be off.
