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. [. . . ] If you replace the probe, you should recalibrate. First connect the temperature probe to the meter. 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. The LCD shows "CA" momentarily and a value flashes. Press MAX/ or MIN/ key to adjust the displayed value until it matches the correct temperature. The MAX/ or MIN/ key will scroll to the maximum allowable value. 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. 7. Press ENTER key to confirm calibration. 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. MEASUREMENT 4. 1 Taking Measurements 1. 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. 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.
