Holding a Temperature Display

1.The “HOLD” key is located on the right side of the Thermometer face and is one of the four buttons surrounding the “TYPE” button. Pressing the “HOLD” key will cause the Thermometer to display the present readings. It will display only the present reading and will stop all future measurements-see Figure 1.

2.To turn off the “HOLD” setting, press the “HOLD” key again. This will resume normal display on ongoing measurements-see Figure 1.

Backlighting the Display

The Thermometer has a backlight feature which allows you to read the Thermometer display in situations where there is not enough light-see Figure 1.

1.Press the Backlight key to light up the display.

2.Press the Backlight again to turn the backlight off.

Overload Display (1)

The digital display will indicate “1” when the input exceeds the measurement range selected-see Figure 1.

1.If the temperature you are measuring exceeds 199.9, change the display to read in increments of 1-see section on Selecting Display in 1 Degree or Tenths of a Degree.

2.Make certain that the thermocouple connector is seated properly and that the leads are not broken.

Thermocouple Checking

1.First, allow time for the Thermometer to adjust to the ambient temperature. To check the accuracy of the Thermocouple reading, place the end of the Thermocouple away from any object. Press the Thermocouple Checking button (Tc) button. With the button down, the Thermometer will display the temperature reading inside the unit. Record the temperature reading.

2.Release the button and allow time for the Thermometer to adjust to the ambient temperature. The Thermometer will display the exterior temperature. Record the temperature reading.

3.The Thermocouple is reading correctly if the two temperatures are reading within the accuracy range specified on page 2. For example, when the thermometer reads 74.7°F with the Tc button on, and 74.2°F with the button off. There is a .5 degree difference in temperature shown.

4.The degree of accuracy is + 4°F, or + .5% reading plus 2°. The reading is within this range and is accurate. Note that if accuracy is off it is generally a problem with the

Thermocouple and not the Thermometer.

Tripod

The Thermometer can be set onto a Tripod (not included). Thread the receptacle on the back of the Thermometer onto the screw of the Tripod-see Figure 2 next page. The thread on the tripod mount is 1/4”-20 and can be used with a tripod which fits this same size thread.
