Operation 1. : Power ON/OFF Key. Press the power button to turn the power ON or OFF. 2. °C/°F/K: The Temp. Unit Selection Key. Press the key to sequentially alternate the three temp. units of °C, °F, and K. 3. HOLD: The Readout Hold Function Key. Press the “HOLD” key, a “HOLD” icon will display on the LCD and the readout will be held in; press the “HOLD” key once more to cancel the “HOLD” function. 4.
Operation 5. REL: The Minus Relative Readout Function Key. Press the “REL” key, a “REL” icon will display on the LCD and the original temp. will go to 0 and save the original temp. to make a standard value. Whenever the input temp. shifts, the LCD will show the minus value of the original temp. value and input temp. value. 6.1°: 1° or 0.1° Unit Selection Function Key Press the “1” key, the whole resolution will become 1°C.1°F, and eliminate the dot.
Operation 8
Operation 8. TYPE: Select a thermocouple type function key. HH147 includes seven diffferent thermocouple types.
Operation 8. COUNT: The Count Time Setting Function Key. The max count time is 99 hours and 59 minutes. 10. TIME: To set the present time function key.
Operation 11
Operation 13. LIMIT: To Enforce Alarm Function Key NOTE 1: The alarm will continue to be activated when the main display temp. value is higher than the alarm setting Hi temp. value or lower than the alarm Lo setting value. 2: The Hi/Lo setting temp. values of the thermocouple types vary.
Operation 13
Operation 15. CLOCK: To Enforce Date Setting Function Key.
Operation 16. Perpetual Calendar: Backlight: A. Press the backlight button to turn the backlight ON or OFF. B. If you do not disable the backlight feature, the backlight will stay on for 1 minute.
Operation 1. RS-232: When you turn on the “RS-232” function the auto power off and the power off will be cancelled. 2. REC: When you turn on the “REC” function the reading value of the meter will transmit the settlement of interval in time, and will write down in the memory in real time. The maximum number of records is 10000 records at most. When turning on “REC” function, the auto power off and the power off will be cancelled. When the memory is filled, the display will show “ou”.
Operation 3. CALL: The HH147 can display the data of every channel, and can also inquire about the surplus space of the memory. When the “CALL” function is on, the auto power off will be cancelled.
Operation : When the RS-232 function is on the biggest settlement time is 59 minutes and 59 seconds. Minimum set time is one second.
Operation 19
Operation : When the record interval function is on, the biggest settlement time is 59 minutes 59 seconds. Minimum set time is 1 second.
