1 Introduction
Model 6850 is as micro-manometer with high precision for measuring differential pressure of
non-corrosion air. It’s available to measure air velocity and air flow when using Pitot. Data storage and
exporting functions make user operating more convenient.
1.1 Features
Measure differential and static pressure from -2500 to +2500 Pa.
Calculate and display velocity and air flow when using a Pitot tube.
True color LCD display differential pressure, air flow and velocity at meantime.
Stores 10000 samples, available for data browsing, statistics, exporting and delete.
Directly exporting data to USB disk without a PC connection.

3.1 Power Supply
Two available ways for power supply: Batteries or AC Adapter.
(1) 4 AA-size batteries can be used for a power supply.
(2) Open the back cover, insert the batteries as under the +/- indication.
(3) Tightly lock the back cover after batteries insert.
Note: New alkaline battery or rechargeable Ni-MH battery can be used. Never mix battery types, or
battery leakage or damage to the instrument may occur.
When the AC adapter is connected and batteries are installed, power will be supplied from the AC adapter.
The specification of the AC adapter is: I/P: AC 110-240V 50/60 HZ O/P: DC 5V/ 2A
