1. INTRODUCTION 1.1 Introducing the Temp JKT Thank you for purchasing the Temp JKT meter.
2. GETTING STARTED 2.1 Description of Keypad Functions Temp JKT meter has seven keys on its splash-proof keypad. These keys include o o ON / OFF, CAL, HOLD / ENTER, C/ F, MAX/ or MIN/ key and J-K-T keys. ON/OFF: Powers meter on and shuts the unit off. Meter directly enters measurement mode when you turn it on. CAL: Allows temperature calibration of the meter. HOLD/ENTER: Freezes the measured reading; confirm calibration value.
2.3 Inserting & Removing the Rubber Boot 1. To remove meter from rubber boot, push out from the bottom edges of meter until it is completely out of boot. Ensure that the connector of temperature sensor is not connected. 2. To insert meter into rubber boot, slide in from the top of meter before pushing the bottom edges of meter down to set it into position. Lift up the stand at the back of meter for bench top applications if necessary.
2.4 Inserting New Batteries The battery compartment is found at the back of instrument. To open the battery compartment, push in the direction of arrow and lift up the cover. Note the polarity of battery before inserting into position. After replacement, place cover back and press down until it locks tight.
2.5 Battery Replacement A “LO” annunciator in the LCD alerts you when battery power is running low. Replace with the same type as recommended by the manufacturer. K LO o C Figure 5: Low battery indicator Caution: Power off the meter when changing battery. 2.6 Connecting the Temperature Sensor Insert the 2-pin mini connector plug of the temperature sensor into the connector socket on the side of the meter. NOTE: The negative pin is larger than the positive pin, be sure to properly align the pins.
3. CALIBRATION 3.1 Temperature Calibration The temperature sensor included with your meter is factory calibrated. Over time, the temperature calibration may drift and the probe requires re-calibration. The Temp JKT meter allows you to have a 1-point calibration as fine adjustment by changing its offset value. This is useful if you replace the probe. If you replace the probe, you should recalibrate. 1. First connect the temperature probe to the meter.
6. Press ENTER key to confirm calibration. 7. The LCD displays “CO” momentarily, and the meter then reverts to measurement mode. See figure below.
4. MEASUREMENT 4.1 Taking Measurements 1. Power on the meter. The meter automatically enters Temperature mode. The “J”, “K” or “T” annunciator will display, depending on what probe type was selected the last time the meter o o was used. The C or F annunciator display in your LCD indicate which mode you are taking measurements in. J o C oF Figure 10: J/K/T and temperature annunciators 2. Press the J-K-T key to toggle between type J, K or T mode, until the mode matches probe type selected. Note reading.
4.5 Maximum and Minimum Hold Mode With the Maximum and Minimum Hold mode, the Temp JKT meter can be used as a maximum registering (or minimum registering) thermometer. The meter displays the lowest or highest temperature measured since entering the Maximum or Minimum Hold mode. 1. Power on the meter. The meter automatically enters temperature mode. Use °C/°F key to switch between Celcius and Fahrenheit reading if desired. 2. Press HOLD key. The reading freezes and the annunciator “HO” displays in the LCD.
5. DISABLE AUTO POWER OFF FEATURE By default this meter will auto power-off 17 minutes after last key operation. This is to conserve battery power. The auto power-off feature can be disabled in situation where longer periods of monitoring are desired. NOTE: The meter switches back to auto power-off mode as soon as it is turned off. Procedure: 1. With meter off, press down ON/OFF and MIN/▼ keys together. 2. Release ON/OFF key first and wait for 2 seconds before releasing MIN/▼ key. 3.
6. PROBE CARE AND MAINTENANCE For best results, always clean the temperature probe with clean tissue paper after measurement to keep the probe in good working condition. Wash the probe thoroughly with tap water if necessary to wash off any residue. Should there be any thin oil film sticking on the probe, wash with mild detergent or soap and warm water. Rinse probe thoroughly under running water. Blot it dry and clean off with clean tissue.
