General Introduction

The product is a new portable Surface Roughness Tester

developed by our company. Featuring high accuracy, wide

range of application, simple operation and stable

performance. It is widely applicable in testing surfaces of all

kinds of metals and non-metals. Integrated pick up within

the main unit, it is a hand-held set, especially suitable for

use on production sites.

 Appearance using aluminum housing design is durable

and helps eliminate electromagnetic interference.

 By using high-speed DSP processors for the data

processing and calculation, measuring and calculation

speed is greatly improved.

 Uses OLED display for high brightness and high quality

fonts, wide temperature range and is suitable for various

applications.

 Using lithium ion rechargeable batteries it can work many

hours with no memory effect. The meter also can work

while charging and charging time is short, while the

battery life is long.

 Uses common USB interface to charge and

communicate. Use special charger or the computer USB

port to charge.

 Dot matrix LCD display making interface message clear.

 Real-time monitoring of lithium battery power and display,

timely reminds users.

 Automatic shutdown function, low power consumption

and hardware design make instrument working hours

plentiful. It is suitable for all kinds of field use.

 The sensors head has a protection door, which protects

the head of the sensor effectively further guaranteeing

the accuracy of measurement.

Work Principle

When the pickup it triggered, it is making a linear uniform

motion along the test surface, the contact stylus is

perpendicular to the work surface and is moving up and

back. Its motion is converted into electric signals which are

amplified, filtered and transformed into digital signals and

processed by the DSP into Ra and Rz values before

displayed on the screen.

Operational Measure

5.1

Remove instrument, right now the sensors head door

should be closed ( see illustration below).

Move to the right to trigger measuring head door switch.

Measurement preparation

Open the sensors head protection door, to expose the

sensor head and prepare to measure.

7

5.2

Depress on/off button. After sound indication (beep),
place device on surface to be measured. Depress red
button on top of device. This puts device in measurement
state. Measuring parameters and sampling length will keep
the last settings/readings before the shutdown of the meter.

Depress on/off button a second time to shutdown. In 3
minutes of inactivity the instrument will be turned off.

Switch on Switch off

Before measuring the user should set up parameters such

as Ra Rz Rq Rt，and the appropriate sampling length and

units imperial if required.

5.4

When the parameters are set up and the cut-off samples

length is decided, it will come to measurement. Point the

Stylus mark to the measured area stably and then

press the Start Key on the top to start measurement, OLED

will read “Testing”. At this time, it will be invalid to press the

start button.

After the “Testing” has disappeared two audio indications

will sound indicating the measurement has being finished,

and the screen will show the measured value.

Measuring

Note:

1) During the pickup’s travel, do your best to make sure

the tester is on the measured surface stably so as to

avoid its influence to the precision.

2) During the pickup return to its previous position, the

tester will not make any response to further

operation.

3) If the tester battery is dying, you must press the
Reset Key , and then you can use it again.

5.5

Before use, calibration should be done with the standard

sample plate. For example, there is a standard sample

plate pointed to 3.14.

In shutdown condition, Press and hold the start button.

Release the start button. The tester will enter the status of

Calibration as shown below.

Calibration

Press the Up Key and Down Key to adjust the displaying

value to the value 3.14.

ut the instrument in the scribed line area. Sensor taxiing

direction perpendicular to the scribed line of texture

direction. Press the Start Key to exit the status of

Calibration. Repeated calibration could improve precision.

9

After measuring, the new standard sample plate value will

be stored to the memory instead of the old one.

If the user has multi-reticle sample plate, he can choose the

suitable sample plate to calibrate the tester against his

measuring range in common use. This way, the tester’s

precision can be improved greatly.

5.6

Plug the charger into the tester’s recharge socket and have

the tester recharged together with the battery

symbol lighting (if no lighting, plug it again). 3 hours

recharging-time is enough. Filled animation end.

Even in shutdown condition charging interface will be

displayed.

Battery Recharge

Daily Maintenance

Maintenance

 Protect the tester from collision, violent shock，heavy

dust, dampness, oil stain, corrosive agents, and strong

magnetic field etc.

 Please switch off in time after each measurement to

10

save the energy, and have the battery recharged

promptly when necessary.

 The sensor is the precision part of the tester and

particular care should be taken of it. After each use,

put on the protective sheath gently to avoid violent

shock to the sensor.

 Standard sample plate provided with the tester should

be given special protection to avoid scratches that may

make the calibration inaccurate.

6.2

If any trouble occurs, user should not try to dismantle and

repair it. The device should be returned to the manufacturer

for checking and repair, together with the warranty card and

the specimen provided and a statement about the trouble.

Please keep in constant touch with the marketing

department of our company or our sales agents.

on the work-piece surface composed by peak and valley

with small interspaces.

 Sample Length is the benchmark used to distinguish its

surface roughness.

 Evaluation Length is the necessary length for evaluating

the roughness profile. It may include one or more

sampling lengths.

 Ra: Arithmetical Mean Deviation of the Profile is

arithmetic mean value of the deviation of the profile within

sampling length.

 Rz: The maximum Height of Irregularities is the distance

between maximum depth of the profile peaks and

maximum depth of the profile valley within the sampling

length.

 Rq: Root-mean-square Deviation of Profile

Rq is the square root of the arithmetic mean of the

squares of profile deviation (Yi) from mean within

sampling length.

 Rt: Total Peak-to-Valley Height

12

Rt is the sum of the height of the highest peak and the

depth of the deepest valley over the evaluation length.
