4-2 Measuring Procedure
4-3 Thermocouple Measuring Procedure
1. Power on the meter by pressing the “ Power Button” (4-2, Fig. 1). The meter will go through a
short self test.
2. Select the sensor type by pressing the “ Sensor Button” (4-5, Fig.1). As you press this button
multiple time the meter will display the sensor type along the bottom of the LCD. You will see it
change between K, J, T, E & R.
3. Once you have set it for the desired sensor type, insert the probe in to the “ Thermocouple
Input Socket” (4-10, Fig. 1).
4. Select the unit of measure by pressing the “ °C/°F Button” (4-7, Fig.1).
5. Insert the Thermocouple in to the environment you wish to measure. The LCD will display
the measured values.
4-4 Offset Value Adjustment
In some environments or applications there may be some need to offset the displayed
temperature value. After following section 4-3 follow these steps to set a offset value.
1. Simultaneously press and hold the “Hold Button” (4-3, Fig. 1) and “ REC Button” (4-4, Fig.1).
2. The LCD will display the starting value in the bottom of the LCD and the value in the middle
section.
3. Using the “ Up Button” (4-7, Fig. 1) to increase the offset value and/or the “ Down Button”
(4-6, Fig.1) to decrease the offset value.
4. Release all buttons to go to the normal measurement screen. The meter will now display
measured values with the offset already calculated in to the reading.
4-5 Measuring Considerations
1. When inserting the measurement probes in to the “ Thermocouple Input Socket”
(4-10, Fig. 1), note the correct polarity usually indicated by the size of the plug blades (negative
usually being the wider of the two).
2. For the most accurate reading allow the probe to stabilize when it is being introduced in to
an environment that is significantly different in temperature from its starting point.
4-6 Data Hold Mode
1. During a measurement, press the “ Hold Button” (4-3, Fig. 1) to hold the displayed value on
the LCD. The “ HOLD” symbol will also be displayed on the LCD.
2. Pressing the “ Hold Button” (4-3, Fig. 1) will release the data hold function.
4-7 REC Mode
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.
2. To stop using the REC function, press and hold the “ REC Button” (4-4, Fig. 1) for at least 3
seconds.
