INTRODUCTION This instrument is a 3½ digit, compact-sized portable digital thermometer designed to use external thermocouples as temperature sensor. Temperature indication follows Reference Temperature/Voltage Tables (N.I.S.T. Monograph 175 Revised to ITS-90) for thermocouples. SAFETY INFORMATION It is recommended that you read the safety and operation instructions before using the thermometer.
SPECIFICATIONS GENERAL Display: 3½ digit liquid crystal display (LCD) with a maximum reading of 1999. Polarity: Automatic, positive implied, negative polarity indication. Overrange: -OL is displayed. Zero: Automatic. Reading Rate: one time per second. Low battery indication: the " " is displayed when the battery voltage drops below the operating level. Measurement rate: 1 times/second. Accuracy: Stated accuracy at 23°C±5°C, <75% relative humidity. Dimensions: 195mm(H) x 92mm(W) x 53mm(D). Weight: 365g.
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. ELECTRICAL Temperature Scale: Celsius or Fahrenheit user-selectable. Measurement Range: 0°C to 1767°C, 32°F to 1999°F Resolution: 1°C, 1°F Accuracy: Accuracy is specified for operating temperatures over the range of 18°C to 28°C (64°F to 82°F), for 1 year, not including thermocouple error. ±(0.0% rdg + 2°C) on 0°C to 50°C ±(0.1% rdg + 1°C) on 50°C to 1767°C ±(0.
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 5 °C °F Selecting the Temperature Scale Readings is 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 or °F key.
6 MIN MAX record Mode Press MIN MAX key to enter the MIN MAX Recording mode, (displays the Maximum reading, Minimum reading, "MAX-MIN" reading and Average reading stored in record mode). In the this mode the automatic power-off feature is disabled and key and all function key are disabled.The beeper emits a tone when a new minimum or maximum value is recorded. Push MIN MAX key to cycle through the MAX, MIN, MAX-MIN and AVG readings.
7 8 9 TIMER STOP-WATCH Mode (for HH501AR / HH501AS) Press TIMER STOP-W key to enter stop-watch mode stop-watch is displayed. Press START/STOP key to toggle stop-watch starts and stops (Time goes up to 19 minutes & 59.9 seconds). Press CLEAR key to display 0.1 second, then press again to zero the stop-watch. Press TIMER STOP-W key again to exit the stop-watch mode.
11 SET mode (Relative value set and Hi/Lo Limits value set) 1. Press SET key to enter Relative valuse SET mode (Press ENTER key can escape relative valuse set mode), REL set mode. _ = = =.= is displayed (the ".=" is displayed when you set up the fourth number). Relative value is entered via overlay numbers, when you want to get negative values push (- 0) key for end of numbers, then press overlay ENTER key, stored the relative value, enter Hi/Lo Limits value set mode. 2.
12 Hi/Lo LIMITS mode 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 other funtion 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. Press Hi/Lo LIMIT key again to exit the Hi/Lo LIMIT 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. (NEDA 1604, IEC 6F22). 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.
HH501(A,B)K / HH501(A,B)J / HH501(A,B)T / HH501(A,B)E HH508BR/HH508/HH509/HH509R 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 25.6mV to the T1 after the display is stabilized (forward 4 digits), then press “ ENTER “ key and "01" is displayed. 3.
