This digital/analogue servo tester is packed with features. The LCD display makes accessing the host of functions quick and easy while the rotary knob makes programing functions a breeze. This unit can be powered via the balance tabs of a 2S Lipoly battery or via the 7.4v~12v DC input with the included leads.
Modes: ED Endurance mode Cycles your servos for endurance testing. FP Offers a 3 point test, great for testing the centering ability of your servo. DB Dead Band testing will show the dead band of a servo within 30us SP is a speed testing mode that will give you a ms reading for a 60deg travel. WP is an auto mode that will swing the servo left to right at a user selected speed. PW is a pulse width test mode, this mode will display the pulse width of a connected servo.
Specs: Servo Type: Digital / Analog Pulse Width Digital: 500~2500us Power input: 2s Lipoly or 7.4~12V
The speed test failed to complete on about half of the servos that I have been testing today. When I press the Enter key to start the test, the servo travels swiftly in one direction, pauses briefly, then swings to the other side at full speed - taking the expected 1/10th of second to travel what looks like 60 degrees.... but then nothing happens. he results screen does not appear and the servo just sits silently. When it is working correctly, the results screen appears immediately after the servo stops moving. A couple of times the result screen did appear and showed a speed of 3 to 7 sec/60 degrees, which seemed to be consistent with the time that I waited. Incidentally, if the test happens to complete after 10 seconds or more, the result screen will display a letter instead of a number in the seconds position.
Has any body else seen this behavior? Am I doing something wrong, or is this indicative of a problem with the servo? The servo's seem to function correctly otherwise. I haven't flown with them yet.
bought a new turnigy analog/digital servotester.took out of box and powered servotester off brandnew zippy series 4000 3s battery!!!! flipping thru settings it stayed on for 5 minutes and screen all of a sudden turned black?????????? tried brand new 2s battery same thing???? black screen ???
I've brought loads of servos off of HK with the mounting hardware like rubber grommets and screws,i know they sometimes don't give you that sort of gear with the sub micro,micro servos because most people glue them into foam planes, here is just one i sometimes use which has the mounting gear,PRODUCT ID: DS-929MG.
Google 'Adruino servo control' and check out some of the projects. That's basically what's inside of this unit. The tiny microprocessor chip does almost everything. It already knows how to control a servo.
NOW I have experience of changing the display into an backlighted one.
The RT0802a is working fine. The backlight is powered by the LM7805. And additional adjustable resistor (5 kOhm) was soldered between the PIN 3 and GND for adjust the displays contrast.
Does anyone hast experience changing the lcd display into one with backlight?
It is an JHD802a - I like to use an RT0802A 8X2 characters LCD module instead of. This RT0802A has on pin 15 an 16 the 5 V and GND. This I will connect to the LM7805 linear voltage regulator.
Does anyone did this before?
Does anyone know more about this tester?
Thank you kind regards
I am planning on using it mostly for 1s applications. Does the fact that it runs on a 7.4 V mean that it feeds 5V to the servo? Is this adjustable? I would love to be able to determine the PW of servos to better find alternatives with some of todays finicky 3 axis rx's. I need to safely run 1s servos though. Should I stick with the simpler testers that you put out the same voltage you supply at input to be safe?
Anyone know how the PW- Pulse Width test works? I choose PW mode and press enter. the unit says"init...waiting", then "p_width US". I`ve tested several servo`s, but it seems like it doesn`t get a US reading?
I have a similar one from ebay (Manufacturer G.T.Power) and with that you can select "Analog" or "Digital". I have measured pulses and frequencies and found that "Analog" equals 50Hz, while "Digital" equals 100Hz. There are no other methods to determine pulse rate.
Yes i could, but why does it not come what way. This would out of the box replace my servo tester. But, i cant hook it into a plane to test all the servos without more work. If they would have used a JST or servo lead, it would have been a clean product without the extra cable.
Schade habe mir mehr versprochen. Pulsweitentest funktioniert ueberhaupt nicht. Der Speedtest bei schnellen Servos ist ungenau oder klappt nicht. Geraet sollte nochmal ueberarbeitet werden oder ich habe ein Ausschussteil erwischt. Conclusion: improved

This isn't worth the money. You are much better of getting the MT1, which for few bucks more, will give you a lot more functionality and flexibility. The MT1 also has a manual.
The hardware is actually good layout it's just the program functionality is crap. I was hoping to be able to reprogram, but couldn't since could even see IC chip when I opened it up.

For my needs, better than the MT-1 previuosly purchased from HK. It lacks a few features compared to the MT-1, however it has a lcd display rather than the yesteryear red led display of the MT-1, which is just about un-readable now. You can only test one servo at a time, not a big issue, unless you spend all day checking servo's! No manual is a minus, however, a brief description of the functions are printed on the box so don't throw it away before reading them.
