INTRODUCTION This instrument is a 4½ digit, compact-sized portable digital thermometer designed to use external K/J/T/E/R/S/N-type thermocouples as temperature sensor. Temperature indication follows Reference Temperature/Voltage Tables (N.I.S.T. Monograph 175 Revised to ITS-90) for K/J/T/E/R/S/N-type thermocouples. One K-type thermocouple are supplied with the thermometer. SAFETY INFORMATION It is recommended that you read the safety and operation instructions before using the thermometer.

ENVIRONMENTAL Ambient Operating Ranges: 0°C to 50°C (32°F to 122°F) <80% R.H. Storage Temperature: -20°C to 60°C (-4°F to 140°F) <70% R.H. GENERAL Display: 4½ digit liquid crystal display (LCD) with maximum reading of 9999.9. Overload: "----.-" is display. Battery: Standard 9V battery. Battery Life: 100 hours typical with carbon zinc battery. Auto power off: The meter key switch inactive for more than 30 minutes, press power key to resume operation. Dimensions: 192mm(H) x 91mm(W) x 52.5mm(D). Weight: 365g.
OPERATING INSTRUCTIONS 1 Power Switch The key turns the thermometer on or off. In the MIN MAX record mode can not power off, must leave MIN MAX record mode then power off. 2 °C/°F Selecting the Temperature Scale Readings are dual displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). When the thermometer is turned on, it is set to the temperature scale that was in use when the thermometer was last turned off. To change the temperature scale, press the °C/°F key.
4 TIMER STOP-WATCH Mode Press TIMER STOP-W key to enter stop-watch mode stop-watch is displayed in second display. Press start/stop key to toggle stop-watch starts and stops (Time goes up to 99 minutes & 59.9 seconds). In the this mode the automatic power-off feature is disabled. Pess Clear key to zero the stop-watch. Press TIMER STOP-W key again to exit the stop-watch mode.
Push MIN MAX key to cycle through the Max/Min/Avg/Present readings. If an overload is recorded, the averaging function is stopped and average value display"----.-". The true average of all the reading taken over at least 22 hours preiod can be displayed. If 22 hours is exceeded, new averages are no longer calculated. The last calcalated value is retained as the average reading, but the actual minimum and maximum reading will continue to be captured.
8 Hi/Lo LIMITS mode (only Main display) Press Hi/Lo LIMITS key to enter the Hi/Lo Limits comparative mode, "LIMIT" is displayed. In the this mode the automatic power-off feature is disabled and REL key, HOLD key, MAX/MIN key are disabled, when input temperature value exceed Hi. The beeper emits a continuity pulse tone and "Hi" is displayed, and when input temperature value exceed Lo value. The beeper emits a discontinuous pulse tone and "Lo" is displayed.
3. Time set mode, (Press ENTER key can escape Time set mode) = = : = = = = is displayed in third display. Time (hours, minutes, seconds) value is entered via overlay numbers, then press overlay ENTER key. Time start from set time value and exit set mode. 10 Relative value Recall display mode Press REL RECALL key to display the Relative set value on second display. Press REL RECALL key again to exit this mode.
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. Remove the battery from battery contacts.
RS-232 Operation Using Quick BASIC The following example shows how to send command instruction and receive data responses over the RS-232 interface using Quick BASIC. The program example is set up on "COM1".
IF C$ = - THEN DEC = DEC * -1 END IF CLS LOCATE 13, 34 PRINT USING ######.
RS-232 Transmit and Receive Comammand Summary 1. Control letter should use Capital Letter. 2. If you write you own program, the host computer must send the "A" letter to activate data transmission. 3. If you should stop data transmission the host computer must send the "B" letter to extend battery life. 4.
OUTPUT DATA FORMATS The data format consists of 32 bytes.
