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. Two 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. 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 T1 T2/T1-T2 Main display Input Selection The input selection indicates which input is selected for main display; T1 thermocouple, T2 thermocouple or the difference between the two thermocouples (T1-T2), when the thermometer is turned on, it is set to T1, When main display input selected T1, then T1 input can select alternate of thermocouple by pressing TYPE key switch.
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. In the this mode, press HOLD key to stop the recording of readings, all values are frozen, press again to restart recording.
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.
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.
HH 506(R)/HH 507(R) CALIBRATION PROCEDURE Note: The following calibration procedure should perform only by qualified technicians who have access to the items as following. Equipment: The class of calibrator had better 10 times greater than the measured meter. 1. Set the jumper position on J1 position. 2. Input DCV 17mV to the T1 after the display is stabilized (forward 4 digits), then press “ HOLD “ key and "0.0" is displayed in main display. 3.
