Page 3: Introduction
INTRODUCTION This versatile handheld instrument provides highly accurate temperature measurements. The instrument is designed for easy operation and includes the following features: Operator selection of Celsius or Fahrenheit scale Resolution of 0.1°C/F from –199.9 to 999.9° Large backlit LCD with two lines of four-digit display Hold feature for temporarily retaining a reading... -
Page 4: Safety Precautions
SAFETY PRECAUTIONS WARNING: This instrument is designed to accept low level signals supplied by standard thermocouples. Under NO circumstances should the input voltage exceed the specified 50V RMS. To prevent ignition of a hazardous atmosphere, batteries must only be changed in an area known to be nonhazardous. -

Page 7: Battery Installation And Replacement
BATTERY INSTALLATION AND REPLACEMENT The total battery life without backlighting is about 750 hours. Each bar of the battery annunciator represents 200 hours. A blinking empty battery annunciator indicates 150 hours remaining. Selected settings are stored in memory and will remain in memory even after power is turned off, or while batteries are being replaced. -
Page 8: Inserting And Removing Rubber Armor
INSERTING AND REMOVING RUBBER ARMOR 1. 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. -
Page 9: Assembling Optional Hands-Free Accesories
ASSEMBLING OPTIONAL HANDS-FREE ACCESORIES You can use the optional magnets and strap in the Hands-Free Kit accessories for hands-free operations. - 7 – GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com... -
Page 10: Self Test
SELF TEST Press the on/off key. The meter performs a self-test and all display digits and indicators, should remain on for approximately one second. The thermometer will then display the thermocouple type and resume to the measurement mode. CONNECTING A THERMOCOUPLE Use the correct thermocouple type for your instrument. - Page 11 Thermocouple wiring polarity must be correct. If readings decrease as the temperature increases, the thermocouple wires may be reversed. The red wire is negative for thermocouple wires manufactured in North America. - 9 – GlobalTestSupply www. .com Find Quality Products Online at: sales@GlobalTestSupply.com...

Page 12: Key Functions
KEY FUNCTIONS Toggle between Celsius or °C/°F Fahrenheit. Activates Calibration mode offset calibration 0°C (after field calibration enabled). Activates/deactivates freezing of the measured hold reading while in measurement mode. Activates/deactivates display of the minimum and maximum readings. Powers on and shuts off the thermometer by holding it for 3 seconds. -
Page 13: Display Overview
10. DISPLAY OVERVIEW Celsius or Fahrenheit indicator. °C/°F Minimum reading annunciator. Maximum reading annunciator. 3 Bars : < 750 hours 2 Bars : < 550 hours 1 Bar : < 350 hours Blinking: < 150 hours Blinks during calibration mode. Remains in display indicating field calibration is active. -
Page 14: Selecting Temperature Scale
If a thermocouple is not connected or if the thermocouple is defective, the display will indicate “OPEn”. Thermocouples are sensitive at the tip or measuring junction. When taking measurements, allow time for the reading to stabilize. Multiplying the time constant of the probe by 5 will give you the approximate time required. -
Page 15: Min And Max Function
13. MIN AND MAX FUNCTION Press the min/max key to toggle between the minimum and maximum readings. This function is ideal for monitoring unattended operations while continually displaying every temperature change that occurs. The minimum and maximum values are sensed and automatically stored. -
Page 16: Canceling A Field Calibration
improve thermometer/probe accuracy or to compensate for thermocouple drift. 1. Pack sensing end of probe in a container tightly packed with crushed ice and filled with distilled water. Allow temperature to stabilize. 2. Press and hold the cal key for 3 seconds to enter the calibration mode, the CAL annunciator on the display starts blinking. -
Page 17: Field Calibration Lockout And Re-Enable
17. FIELD CALIBRATION LOCKOUT AND RE-ENABLE The calibration lockout feature prevents any field calibration changes. The lockout remains in effect until a lockout re-enable has been performed. Use the following procedures to lockout or re- enable the field calibration operation. LOCKOUT PROCEDURE 1. -
Page 18: Maintenance
18. MAINTENANCE Properly used, the thermometer should maintain calibration indefinitely and not require service other than occasional cleaning of the housing and changing of the batteries. 19. CLEANING WARNING: TO PREVENT IGNITION OF A HAZARDOUS ATMOSPHERE BY ELECTROSTATIC DISCHARGE, CLEAN WITH DAMP CLOTH. Do not clean with abrasives or solvents. -
