SRG-4500 OVERVIEW
Outline of the SRG-4500
The SRG-4500 is a portable, lithium-ion battery powered instrument used for checking
surface finish with the measured values displayed on a digital readout. This instrument can be
utilized in a laboratory setting, a shop inspection area, or wherever on-site surface roughness
testing is required.
Note:
Although this instrument is designed and built to withstand the rigors of handling and usage,
it is a sensitive precision instrument and should be treated with care to assure measurement
accuracy and reliable performance.
Measurement principle
Skid type surface roughness testers are common instruments used on the shop
floor. A diamond stylus is traversed across the specimen and a piezoelectric
pickup records all vertical movement. Peaks and valleys are recorded and
converted into a known value of a given parameter.
Features of SRG-4500
15 parameters: Ra, Rq, Rz, Rt, Rp, Rv, RS, RSm, Rz(JIS),
Ry(JIS) ,RSk, R3z, Rmax, RPc, Rmr
High accuracy inductance pickup;
Four filtering methods of RC, PC-RC, GAUSS and D-P;
Compatible with four standards of ISO, DIN, ANSI and JIS;
Can store 15 sets of measurements results
128×64 dot matrix LCD displays all parameters and graphs;
Data processing with high speed and low power consumption;
Built-in high capacity lithium ion chargeable battery. Consecutive work time is longer than 20 hours;
Can be connected to your PC printer to print all parameters and graphs;
Built-in standard RS232 interface enables communication with PC;
Automatic switch off, memory and various prompt instructions;
Optional printer, analysis software and measurement platform.

Turning On/Off the Power Supply
TurningOn/OffBatteryswitch
The battery switch is on the right rear side of the instrument. When powering off for the
night, this switch should be placed to the OFF position to cut off power supply. The SRG-4500
will automatically power on when the switch is moved to the ON position.


TurningOn/OffPowerbutton
Power button is located in the lower-left corner of keypad. Use this power button during
normal usage. If the unit will be off for an extended period of time, the battery switch (mentioned
above) should be switched to the OFF position. All data will be saved using either battery switch
or keypad button.
Battery Charging
There is a battery symbol in the top right corner of the SRG-4500. When all of the black bars
inside the symbol disappear, the battery is low and the unit must be charged up
Please note that the charger has a built-in light. This light will be RED when the unit is charging
and will turn GREEN when the unit is fully charged.
Typically, a charging time is approximately 3 hours .

Measurement operation
Measurement operation
Stylus position
Prior to taking a test, whether on your part or using
the calibration reference standard, the stylus
position must be leveled on the application. The
SRG-4500 has a built-in zero indicator to make this
simple and accurate.
Position the unit on the supplied reference standard
or your work piece and press the Enter (back arrow) button. The leveling indicator will appear on
the display. Using the supplied height adjusters on each side of the unit, raise or lower these slides
until the arrow falls on or close to the “0” in the center of the leveling scale. Once achieved, press
the Enter(back arrow) button to return to the main measuring screen.
Calibration : using supplied reference standard
Accuracy of the SRG-4500 is +/-10% of actual value
Prior to measurement on your parts, you should verify the accuracy of the unit by performing a
quick calibration using the supplied reference standard.
If the difference between the measured value and the specimen value is greater than the
scope of equipment requirements, or user requirements are more accurate, you can use that value
of the calibration function to correct measurement results.
The calibration steps are as follows: (Must be Calibrated in METRIC mode only)
1) Calibration
Press and Hold the Set/Menu button to bring up the
main menu. Use the up or down arrow buttons to scroll
down to Calibration. Press the Enter (back arrow) button to
enter this parameter.
.
2) Setting correct values
Press the down arow button to choose the closest
roughness value of your part. In other words, if the
roughness of your part is approx. 5µm, you should set
the calibration on the+/-20µm setting. If your part is
approx. 47 µm, you should set calibration under +/-40
µm, etc.
