EMCS Servo Tester(short as EMCS-ST) is a new tool for R/C user. It can test basic and advanced functions of servo, help you to fix helicopter or other R/C model. It can also used as a alternative of transimiter, you can use it to test the receiver, ESC, etc.

There is the main characteristics:
1. Linear Output. The tester outputs standard servo signal, turning the knob can change the signal and display on the screen. This function is used for testing servo's rotating range and shanking point.
2. Fix Point Output. According to the menu, the tester can output three servo signal of LOW, MIDDLE and HIGHT. This function is used for testing the positioning capability of the servo, espacially whether the servo can work normally after a period of working.
3. Deadzone Test. This funtion is used to test the respond thredhold of the servo,known as the servo sensitivity. This funtion is usually used to match the interrelated servos in a model.
4. Speed Test. This funtion tests the time need to rotate form 0 degree to 60 degrees, judging servo's ratate speed. According to multiple testing data, it also can judge the servo's iteration.
5. CW/CCW. The tester can output 10 different speed signals that makes servo rotating clockwise and counter-clockwise continuously. This funtion can simulate servo working state, producers can use this function to test servo's lifetime.
6. Standard Signal Input. This fuction is used to measure the plus width of standard signal of the external device. It is usually used to test whether the receiver(or other servo driven circuit) is normal or not.

Where to use:
1. When you buy new servos in R/C shop, test it in the shop, so you can pick out the bad one.
a. How about the linearity of the servo? Use "Linear Mode".
b. What sensitivity of the servo is? Use "Deadzone".
c. Whether the servos rotate the same fast? Use "Speed Mode".(speed time value is not an absolute value, test two servos in the same condition, you can see if they have similar performance)
2. When you fix servos to heli or fix wings, using "Fix point Mode" to drive the servo to 0 degree, 45 degree, 90 degree.
3. When you are not sure the servos in the plane are in good status, use servo tester to test servos fixed in the plane.
4. Whether your receiver is good or not? connect the receiver and servo tester, use "Standard Signal Input" you can see the pulse time that receiver output according to the stick in transmitter.
5. If you are a dealer, use "CW/CCW" to test a sample servo of a brand, you can find out more information than ever.

Hi emcs,

That looks interesting. How about servo frame rate control, any thoughts on being able to change it to drive digital servos?

Is the tester available for sale or order?

Thanks. :)

hi Cobra
What do you mean about the "frame rate control"? the tester has a function "CW/CCW" to drive the servo rotate at different speed rate.
And the tester can drive all analog servos and digital servos.

Now we do not have agent in USA, you can get it from our company, please contact with my MSN: tech.emcs@hotmail.com
The sales price is $54.99(not including shipping)

i have this tester:
speed testing for 2 servos
1.cheap servo from UH HXT 9320mg , measure :0,274
2. Futaba 3150 ...measure : 0,008
but :real is futaba much slower.
0,274 is faster like 0,008.....? :confused: hier is something wrong...higher numbers...faster servo :confused:
what are this numbers? time in seconds? :eek:
