溫濕度表test-622介紹

INTRODUCTION
This instrument is a portable 31/2 digit., compact-size ddigital thermometer designed
to use external K-type thermocouple as temperature sensor. Temperature
indication follows National Bureau of Stards IEC584 temperature/voltage tables for K-type
thermocouples. One K-type thermocouples is supplied with the thermometer.
Temperature Scale:
Celsius (℃), Fahrenheit (℉) or Kelvin (K) user-selectble
Measurement Range:
-50℃ to 1300℃, -58℉ to 2000℉, 223K to 2000K
Resolution: 1℃ or 1℉, 0.1℃ or 0.1℉,1 K
Accuracy:Accuracy is specified for operating temperatures over the
range of 18℃to 28℃(64℉ to 82℉), for l year, not including thermocouple error.
±2℃---------------------- -50℃ to 0℃
±4℉---------------------- -58℉ to 32℉
±5K---------------------- 223K to 273K
±(0.5% rdg+1℃)-------- 0℃ to 1000℃
±(0.8% rdg+1℃)-------- 1000℃ to 1300℃
±(0.5% rdg+2℉)-------- 32℉to 2000℉
±(1.0% rdg+2K)-------- 273Kto 2000K
Selecting the Temperature Scale
Readings are displayed in either degrees Celsius (℃), degrees Fahrenheit (℉).When the
(℃), degrees Fahrenheit (℉).When thetemperature scale that was in use when the
thermometer was last turned off. To change thetemperature scale, press the For℃ or ℉key.
BACKLIGHT MODE
Pressing the Backlight key to turn on the LCDbacklighting function. Pressing the Backlight key
again to turn off the LCD backlighting function.
Single-Thermocouple Temperature Measurement
The thermometer displays the temperature of the thermocouple that is connected to the selected
input. Press the T2 key to display the temperature of the thermocouple connected to the T2 input.
Press the T1 key to display the temperature of the thermocouple connected to the T1 input. The
input selection cursor indicates which input is selected.
