RuoShui 6801 Operation Manual

Ⅰ. Overview
It is a 3 1/2 digital thermometer which is driven by 3V battery, used for measuring temperature
with large range and high accuracy, can use any K-type thermocouple (Ni-Cr - nisiloy) as the
temperature sensor.
Ⅱ. General feature
1. Display: 3 1/2digit LCD display with max. indication 1999
2. Sampling Rate: about 2.5 times/s
3. Open circuit display of the sensor: Max. display "1"
4. Low battery display: weak battery symbol shows
5. Operating environment: temperature 0℃~50℃, 32℉~122℉ relative humidity ＜ 80%
6. Storage environment: temperature -10℃~60℃, 10℉~140℉ relative humidity ＜ 80%
7. Battery: AAA alkaline battery or carbon zinc battery
8. Battery life: alkaline battery is about 200h, carbon zinc battery is about 100h
9. Auto power off: about 15 mins

Note: 1. In order to ensure the measuring accuracy, it's better to measure after turn on and warm up the
meter for 3 minutes.
2. The accuracy in the form above excludes the errors of thermocouple, refer to the accuracy of
the probe for revising during the measurement.
