Frequently asked questions
Does the tester work with any servo?
Check the servo datasheet to see if it is compatible with the tester’s voltage range.
Can I use a different power supply than the one specified?
No, use a power supply between 4.8 V and 6.0 V.
Does the test button need to be held down constantly?
Press the button only to perform the test, leave it in its normal position otherwise.
Does the tester automatically adjust the servo motor?
No, manually adjust the servo motor with the potentiometer on the tester.
