User manual EUTECH INSTRUMENTS ECOSCAN TEMP JKT TEMPERATURE METER

[. . . ] INTRODUCTION 1. 1 Introducing the Temp JKT Thank you for purchasing the Temp JKT meter. This economical microprocessorbased handheld meter works with type J, type K and type T probes for a wide temperature measurement range: · · · Type J probes (iron-constantan) offer a wide range of ­200 to 1000 °C / 328 to 1832 °F; use in reducing environments Type K probes (chromel-alumel) offer the widest range of ­250 to 1372 °C / -418 to 2502 °F; use in oxidizing environments Type T probes (copper-constantan) of range of ­250 to 400 °C / -418 to 752 °F; good for ambient and sub-freezing measurements The Temp JKT meter features: · · · · · · · · Large LCD for clear and easy reading Readings in C and F (selectable) Minimum and maximum temperature display Minimum and maximum hold mode Low battery indicator Hold function, freezes measured reading User calibration - offset adjustment Built-in memory backup; calibration and other information remain if battery is disconnected o o This instruction manual is organized for quick reference with step-by-step procedures that give you thorough review of the various features and meter operations. Included with your meter are a rubber boot, 4 alkaline "AAA" batteries, an instruction manual and a warranty card. To order different type of thermocouple probes, please refer to Section on Accessories for more information. 1 2. [. . . ] 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. Press ON/OFF key to power up the meter and wait for meter to enter measurement mode. Dip the probe in a constant temperature bath, or in liquid whose temperature can be checked with an accurate thermometer. For best accuracy, place the probe and thermometer in a constant temperature bath. To enter temperature calibration mode, press and hold CAL key for 5 seconds before release. Press MAX/ or MIN/ key to adjust the displayed value until it matches the correct temperature. NOTE: The maximum adjustments allowed for the following meter series from factory default are: · · EcoScan JKT Temperature meters = ±10 °C EcoScan 4/5/6 Temperature meters = ±5 °C 3. The LCD displays "CO" momentarily, and the meter then reverts to measurement mode. See figure below. Press down CAL key for 5 seconds before release °C CAL °C From measurement mode °C HOLD ENTER °C Figure 8: Temperature calibration 7 4. 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. Press the °C/°F key to toggle between each measurement mode. 4. 2 Displaying Maximum and Minimum Readings The Temp JKT meter can momentarily display the maximum and minimum temperature measured since you switched the meter on. The "MAX" or "MIN" annunciator displays in the LCD and the maximum or minimum temperature momentarily displays. Meter then returns to measurement mode. K MAX o C Figure 11: Viewing the maximum & minimum value 4. 3 Holding a Reading To freeze or hold your reading, press HOLD key once. The LCD displays "HO" annunciator to indicate the HOLD function is activated. K HO o F 4. 4 Releasing a Held Reading Figure 12: HOLD it Press HOLD key again to deactivate HOLD function or to release your frozen reading. The meter returns to measurement mode, and the "HO" annunciator disappears from the LCD. 8 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. Use °C/°F key to switch between Celcius and Fahrenheit reading if desired. The reading freezes and the annunciator "HO" displays in the LCD. [. . . ] TROUBLESHOOTING Problem Power on but no display Cause a) Batteries not in place. Solution a) Insert batteries. d) Remove or switch off interfering motor. "oPEn" display on LCD "Ur" or "Or" display on LCD "LO" annunicator in the LCD Unstable reading a) Probe not connected a) Measurement over (Or) or Under (Ur) range a) Low battery a) Electrode not deep enough in sample b) Dirty probe c) Broken probe d) External "noises" or induction caused by nearby electrical motor Slow response a) Dirty probe a) Clean probe 11 8.
