Page 3: Safety Information
This instrument is a 4½ digit, compact-sized portable digital thermometer designed to use external K-type and J-type thermocouples as temperature sensor. Temperature indication follows Reference Temperature/Voltage Tables (N.I.S.T. Monograph 175 Revised to ITS-90) for K-type and J-type thermo- couples. Two K-type thermocouple are supplied with the thermometer. -

Page 6: Operating Instructions
OPERATING INSTRUCTIONS Power Switch key turns the thermometer on or off. In the data SET mode, can not power off, must leave data SET mode then power off. °C/°F Selecting the Temperature Scale Readings are dual displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). - Page 7 The K/J key switch the T1 input selects the K-type or J-type thermocouple as input, when main display input selected T1. When the thermometer is turned on, it is set to the type selected that was in use when the thermometer was last turned off.
- Page 8 In the this mode, press HOLD key to stop the recording of readings, all values are frozen, press again to restart recording. To prevent accidental loss of MIN, MAX and AVG data, in this mode can only be cancelled by pressing and hold down the MIN MAX key for 2 seconds to exit and erased recorded readings.
- Page 9 Sec. Minu. Selecting the Time scale Reading the third displayed (Time) in either second or minute. When the thermometer turned on, it is set to second. To change the Time scale, press sec. Minu. key. Maximum Time reading is 100 hours. If 100 hours is exceeded, reset Time to zero and restart.
- Page 10 The input selection indicates which input is selected for second display; T1 thermocouple, T2 thermocouple or the difference between the two thermo- couples (T1-T2), when the thermometer is turn on, it is set to T2 input can select alternate of thermocouple by second display K/J key switch.

Page 11: Operator Maintenance
OPERATOR MAINTENANCE WARNING To avoid possible electrical shock, disconnect the thermocouple connectors from the thermometer before removing the cover. Battery Replacement Power is supplied by a 9 volt "transistor" battery. The " " appears on the LCD display when replacement is needed. To replace the battery, remove the two screws from the back of the meter and lift off the battery cover. -
Page 12: Calibration Procedure
CALIBRATION PROCEDURE Note: The following calibration procedures should be performed only by qualified technicians who have access to the following: Equipment: The class of calibration should be 10 times greater than the measured meter. Step 1: Short the J3 with jumper. Step 2: Apply 65 mV to the T1 input from Volts Calibrator and wait till the reading becomes stable, then press the SET key until the display shows 0.1. - Page 13 NOTES:...
