QUICK START GUIDE To ensure best results please read the complete manual. Connect probe. Press the on/off key. Press again to turn on backlight. Select °C or °F display using °C/°F key. Insert probe in sample. Allow adequate time for reading to stabilize.
INTRODUCTION Thank you for choosing the Temp-14 Thermistor Thermometer. This sturdy handheld thermometer provides highly accurate temperature measurements using thermistor probes. The Instrument is easy to use and includes the following features: • Operator selection of Celsius or Fahrenheit scale •...
SAFETY PRECAUTIONS Voltages present at the thermistors may also be present at the battery terminals. Always disconnect the thermistor when changing batteries. W W ARNING This instrument is designed to accept low level signals supplied by standard 400 series thermistors. Under circumstances should the input voltage exceed the specified 10 v rms.
SPECIFICATIONS Range –40 to 150 °C (–40.0 to 302.0 °F) Resolution 0.1 °C (0.1 °F) ±0.2 °C (±0.4 °F) in range -40 °C to 125 °C (-40 °F to 257) Accuracy ±0.5 °C (±0.9 °F) in range 125°C to 150 °C (257to 302 °F) 4+4 digit, 58 X 40mm dual-line Lcd Display display with backlight...
BATTERY INSTALLATION AND REPLACEMENT Voltages present at the thermistors may also be present at the battery terminals. Always disconnect the thermistor when changing batteries. Weak batteries should not be left in the instrument. Dead batteries can leak and cause damage to unit. The typical battery life is about 700 hours.
INSERTING AND REMOVING OPTIONAL RUBBER ARMOUR To insert thermometer into the optional rubber armor, 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.
ASSEMBLING OPTIONAL HANDSFREE ACCESORIES You can use the optional magnets and strap in the Hands Free Kit accessories for hands-free operations. Figure 1: Hands Free Kit - 7 -...
CONNECTING A THERMISTOR Use the correct thermistor (series 400) for your instrument. Using an incorrect probe will result in erroneous readings. (Series 500 thermistor probes may be used along with the supplied correction chart to convert meter readings to actual readings to actual temperature). Insert the ¼...
KEY FUNCTIONS Figure 3: Keypad Toggle between Celsius or Fahrenheit. °C/°F Activates Calibration mode for 0°C offset calibration (after field calibration enabled). Press and hold this key for 3 seconds to enter Calibration mode if field calibration is unprotected. Activates/ Deactivates freezing of the hold measured reading while in measurement mode.
11. MEASUREMENT MODE Press on/off key. thermometer performs a self-test and all display digits and indicators should remain on for approximately seconds before meter enters measurement mode. If a probe is not connected or if the probe is defective, the display will indicate “OPEN”. °c Figure 5: Display when no probe is detected For optimum instrument accuracy, allow one...
12. SELECTING TEMPERATURE SCALE °c 24.6 °C/°F °F 75.4 Figure 7: Press °C/°F key to toggle between °C and °F Select °C or °F by pressing the °C/°F key. Each time the key is pressed, the temperature scale will switch. Switching between °C and °F can be done at any time during operation.
The CAL function allows single point calibration thermometer 0°C (32°F) compensate for probe offset error. Use the field calibration feature improve thermometer/probe accuracy. Temp-14 Thermistor comes with calibration lock function to prevent accidental changes calibration settings. field calibration can only be performed when the function has been unlocked.
with distilled water. Allow temperature to stabilize. 2. Press and release the cal key for 3 seconds to enter the calibration mode. The CAL indicator starts blinking. Release the cal key. 3. If the measured temperature is from –5°C to 5°C (23 to 41°F) when the temperature reading is stable, press the cal key.
17. FIELD CALIBRATION UNLOCK The calibration unlock feature enables field calibration operation. To unlock field calibration: 1. Turn the thermometer off. 2. Hold the cal key and hold key down simultaneously, then press the on/off key. 3. The “CAL” indicator appears momentarily with the version-model window to indicate that the user-calibration function has been unlocked successfully (Figure 9).
18. FIELD CALIBRATION LOCKOUT The calibration lockout feature prevents any field calibration changes. The lockout remains in effect until an unlock has been performed. To lock the field calibration operation: 1. Turn the thermometer off. 2. Hold the cal key and °C/°F key simultaneously, then press the on/off key.
19. MAINTENANCE Properly used, thermometer should maintain calibration indefinitely and not require service other than occasional cleaning of the housing and changing of the batteries. Do not clean with abrasives or solvents. Use mild detergents; never immerse nor use excessive fluid.
