GENERAL
The Phase II model no. SRG‐2200 Mini Surface Roughness Tester is a next generation of
product developed by the Phase II Metrology Group that features high accuracy, a wide
range of application, simple operation and stable performance. It is widely applicable in
testing surfaces of all kinds of metals and non-metals. Integrating the sensor with its
mainframe, it’s a hand-held set especially suited for use on any production site.

WORKINGPRINCIPLEANDSTRUCTUREFEATURES
WORKINGPRINCIPLE
When the motorized sensor is making a linear uniform motion along the test surface, the
contact stylus being perpendicular to the work surface, moves up and down with the work
surface. Its motion is converted into electric signals, which are amplified, filtered and
transformed into digital signals through a/d. The signals are then processed by the CPU
into Ra, Rz,RqandRt values before being displayed on the screen.

USEANDOPERATION
OPERATION:
POWER ON THE DEVICE.
Press and hold the button on the top panel. The display will show the model and serial number and
then the device is ready to work. The 1.14” IPS TFT display will show the measuring parameters and
sampling length of the previous test.
POWER OFF: Press and hold the button for a few seconds until the display turns off.
Before taking a test, choose the desired parameter Ra, Rz, Rq, or Rt and proper sampling length 2.5(0.10),
0.8(0.03) or 0.25(.01) (for sampling length option, consult the appendix).
After switching on the device, press the to change parameters.
To choose the proper sampling length, press the keypad button (0.25, 0.8OR 2.5).
After the parameters and sampling lengths are taken, you may begin testing.
Position the unit over the test area and press the start button on top of the unit. The stylus moves
automatically. When the value on the display blinks twice, the measurement has been completed and the
results shown upon the display.

POINTSFORATTENTION:
While the stylus is in motion, you must keep the device even and steady so as not to affect the accuracy of the
reading.
Before the sensor returns to the original position, the device will not respond to any keypad operation until
the measurement is completed.
CALIBRATION
When abnormal errors are found, the supplied reference standard should be used for calibration. The Ra
value of the supplied standard is 119.5µin (3.03µm).
METHOD: Place the unit on the reference standard so the stylus can run across the 119.5 patch. Take a test. If
the value of the test is outside the allowable tolerance then follow these steps:
Press and hold the button for about 4 seconds and the display will be as shown below:
Press the button to toggle to the column that need to be changed. Use the Up and Down buttons to
adjust the numbers. See example below.
Once the correct value is entered, press and hold the for approx.. 4 seconds to save the calibration.
The value displayed at the end of this process should fall within the allowable tolerance of your test sample.
Normal measurements can resume at this time.


CONVERTINGIN/MM
Press and hold the keypad for about 2 seconds. The system will convert from Metric to English or English
to Metric
BATTERYINDICATOR
When the battery % symbol is near 10% then its time to change the battery in the SRG-2200. Remove the 2-
screws from the backside cover. remove the battery and dispose of properly. Replace with fresh AA battery.
Close the battery compartment. Power the unit on to make sure the battery % is 100%.

MAINTENANCEANDREPAIR
MAINTENANCE
Avoid collision, violent shock, heavy dust, dampness, oil and a strong magnetic field.
The Piezo-electric pick up stylus with diamond tip is extremely sensitive and accurate. After each use, make
sure that the supplied protective cover goes on this tip after each use. Damage to this tip will result in false
and erroneous readings.
REPAIR

ALLREPAIRSMUSTBEDONETHROUGHTHEPHASEIISERVICEDEPARTMENT.
A return authorization number is mandatory in order for a defective tester to be accepted for repair and/or
replacement. All testers must be accompanied by your warranty card or serial number. Complete description
of problem and a contact person for authorization of repairs must be supplied as well.

These values are the average data of many tests,
therefore, slight deviations from the norm do exist.
However, because of the number of tests performed,
reasonable accuracy should be assumed. Because of
the many variables which create this data,
deviations of +/-5% would be considered well
within good measurement parameters.
The relationship between abrasive grit numbers and
surface roughness in terms of micro-inches is
sometimes a basis for speculation.
The values are approximately as follows:
