1.Introduction
Smart sensor AR850 ultrasonic thickness gauge is an intelligent hand-
hold product, which adopts ultrasonic measuring principle, and is
controlled by micro processor, provides quick and precise measurem-
ent of thickness for most of industrial material. This unit is widely used
in various precise measurement for different hardware / parts in indus-
trial realm; one of its important application is to monitor the level of thi-
ckness-decreasing during operation of various and pressure container.
Diffusely applied in manufacture fields, metal processing, and comme-
rcial inspection. The material that conduct and reflect constant sonic
velocity, this product is to be applicable to used.
1. 1 Scope of application
This unit is suitable for measuring materials that are good ultrasonic
conductor such as metal, plastic, ceramic, glass etc., as long as the
measured part in two parallel surfaces for measurement of thickness.
This unit is not suitable for cast iron due to its big crystalloid composition.
1.2 How it work
This unit is comprised of transimtting circuit, receiving circuit, Hi-freq-
uency oscillator, counter, central unit processor, keypad, and moniter
etc., adopting ultrasonic pulse reflect principle. Similar to light-wave
measure principal, the sonic pulse occurs from the unit travels through
the material being measured till reach the interface and reflects back
to determine the thickness of the target material.

6.3 Cleaning the cabinet
Do not use solvent/alcohol for cleaning which erode the cabinet & LCD
window, brush and sweep only with a moist cotton cloth.
6.4 Cleaning the sample block
Because of coupling agent should be put on the sample block during
calibration, after use the sample block should be cleaned for preve-
nting rust. In higher temperature environment, be sure protect the block
form the droplet of water. If the gauge is not use for a long period, please
apply some antirust on the sample block.
6.5 Avoid shocking/impact. Do not store the unit in high humidity enviro-
ment.
6.6 When the tolerance is over than stated in this manual, please refer
to the 3, 4, 5 chapter, in this manual.
6.7 Please contact us or our distributor if the following occurs:
A. Component being destroyed, no readout and enable to measure.
B. Abnormal LCD display.
C. The tolerance is too big in proper operation.
D. Malfunction of keypad.
6.8 This gauge is a advanced technology product, the repairing only by
technician authorized by us, do not try any alterations or repair attempts.
