VICI DM6804A + Instruction Manual

INTELLIGENT DIGITAL THERMOMETER
INSTRUCTION MANUAL

1. GENERAL DESCRIPTION

This multifunctional 4 ½ digital thermometer with highly stable performance and high accuracy is driven by
9V battery. With following features, it's an ideal intelligent tool for temperature measurement:
1.1 Support K, E, J, T, N, B, R, S thermocouples;
1.2 ℃ and ℉ display, data hold;
1.3 Dual display: display the Max/ Min and relative mV value of input temperature;
1.4 Dual channel: measure the T1, T2 and T1-T2 value..
1.5 Memory function: manually record 2500pcs temperature points, and automatically record 6000pcs
temperature points. Recording interval can be adjusted. The longest recording time is about 99 hours.

2. SAFETY REGULATION FOR OPERATION

This instruction manual covers information on operation and safety. For safety and better use, please read the
relevant information carefully before your operation!
2.1 Do not operate this instrument in occasions with stem or inflammable and explosive gas. It's very dangerous.
2.2 Do not input voltage higher than 30V for both terminals. Do not connect T1 and T2 in parallel.
2.3 Wipe the case with a damp cloth and detergent. Do not use abrasives and alcohol to clean the meter.
2.4 Do not disassemble the meter without professional direction.
2.5 For accuracy, please wait 5 minutes to warm up the meter after power on
2.6 Please contact the factory if the meter's accuracy has big error.
