The AR168 is a professional high precision, high range, high resolution
digital pressure gauge for indoor temperature measurement with a large
screen display. It measures the pre-blue detection pressure value relative
to the current atmospheric pressure. The dual channel can simultaneously
detect the pressure dierence between two detection ports. The product
is widely used in natural gas pipelines, air-conditioning refrigeration and
ventilation systems, mechanical hydraulics, plastic molding, bio pharma-
ceutical molding, mining area pressure detection, gas, liquid and
production industrial equipment pressure detection.

up to 100 groups).
b. Long press to exit the storage mode.
c. Press and hold for more than 2 seconds to switch the °C/°F unit.
3. HOLD Button
a. Press to lock and hold the current data.
b. Press and hold for more than 2 seconds to clear the drift zero. (The
data before measurement does not return to zero.
a. Short press to switch up to 12 pressure unit.
b. Press and hold for more than 2 seconds to clear the stored data.
4. UNITS Button
a. Short press to view stored data.

a. Short press to view stored data
b. Press and hold for 2 seconds to enter the maximum and minimum
mode
c. Press and hold for more than 2 seconds to return to the normal
measurement mode

7.PRECAUTIONS
P. 9
1. When the meter is working, keep it away from vibration sources and
strong electromagnetic elds, and environmental locations with
drastic temperature changes, so as not to be interfered and cause
inaccurate measurement data.
2. When measuring corrosive and toxic gases or liquids, please take
precautionary measures to avoid danger or damage to the
instrument
3. Please replace the battery in time when the meter shows a low
battery level and remove the battery when it is not used for a long
time to avoid battery leakage and damage the meter.
4. When measuring the pressure input maximum value, please do not
exceed the scope of the instrument measurement.
5. When measuring the pressure of a single channel, please do not
block the other channel, and do not apply wind or strong airow. At
this time, the meter displays the dierence between the current
measurement port and the atmospheric pressure.
6. When the screen shows over range during measurement, please
disconnect the vent hole. The displayed data will automatically
return to normal. (Pa units can only be displayed up to 9999,
adjustable to kpa units.
7. Before connecting to the trachea, please press and hold the hold
button to clear the zero drift to ensure accurate measurement data
