press and hold the “ Power Button” (4-3, Fig.1) for about 2 seconds.
2. Press “ Function Button” (4-5, Fig. 1) once. You will see a letter J on the top of the LCD.
3. Select the unit of measure, either °C or °F by pressing the “ °C/°F Button” (4-6, Fig. 1). The
LCD will display the unit of measure. For convenience the meter will retain the unit of measure
when it is turned off.
4. Insert the Type J probes into the “ Thermocouple Input Socket” (4-9, Fig. 1).
4-5 Pt 100 ohm Measurements
1. Power on the meter by pressing the “ Power Button” (4-3, Fig.1). Note: to turn the power off,
press and hold the “ Power Button” (4-3, Fig.1) for about 2 seconds.
2. Press “ Function Button” (4-5, Fig. 1) twice. You will see the letters Pt on the bottom right of
the LCD.
3. Select the unit of measure, either °C or °F by pressing the “ °C/°F Button” (4-6, Fig. 1). The
LCD will display the unit of measure. For convenience the meter will retain the unit of measure
when it is turned off.
4. Insert the Pt1 probe into the “ Pt1 Input Socket” (4-10, Fig. 1) and/or insert the Pt2 probe into
the “ Pt2 Input Socket” (4-11, Fig. 1).
4-6 T1-T2 Measurements
1. With the probes already inserted and the meter already setup for either K, J or Pt functions,
press the “ T1-T2 Button” (4-7, Fig.1).
2. The LCD display will show the two measured values on the left side. On the right you will
see the difference of the two measured values.
4-7 Data Hold
While taking measurements you can freeze the displayed value by pressing the “ Hold Button”
(4-3, Fig. 1) once. The HOLD symbol will be displayed along with the held measured value on
the LCD. By pressing the “ Hold Button” (4-3, Fig. 1) a second time will release the displayed
value and turn off the data hold function.
4-8 Data Record (MAX/MIN)
1. To record the maximum and minimum readings, press the “ REC Button” (4-4, Fig. 1). The
REC symbol will be displayed on the LCD. By pressing the “ REC Button” (4-4, Fig. 1) you can
toggle through the Max and Min values.
