## Overview

The Globact RC Digital Servo/ESC Consistency Tester is a compact, high-precision tool designed for RC hobbyists and professionals. It offers 2 microsecond accuracy in servo signal output, supports three selectable modes (manual, neutral, automatic), and can synchronize control of up to 4 servos. Compatible with analog and digital servo signals at multiple frequencies, it ensures precise tuning and testing of steering servos for helicopters, airplanes, and cars while protecting your equipment from damage.

Review: Works great for rc hobbies.
Review: This is a convenient little unit, but it's limited to only 800-2200 μs pulse width, so it only uses about 120°of SG90 servos (which have a range of 500-2500 μs). The "sweep" setting is supposed to be variable speed but its speed is constant, regardless of the dial setting. It doesn't come with any useful instructions (the packaging has very limited info) so I had to look up how to use it on YouTube, and the labeling on the device is unclear. The "S+I" label is actually "Signal, Positive, Negative" and refers to order of the first column of 3 pins (Signal at top). The remaining 4 columns of pins are for servo motors, with the same pin order (Signal, Positive, Negative) as the input pins. Using an external PWM signal overrides all functions of the device (external PWM cannot be toggled from the device), effectively turning 1 servo connection into a 1-channel, 4-port connection. The device will sometimes (erratically) switch between signaling frequencies (50/125/250 Hz) when switching between modes, causing motors to buzz & jitter until the frequency setting is switched back to 50Hz. FYI: the device does NOT show the pulse width of an external signal.

Handy little gadget to use to preset servo to neutral before installation. It also checks moves the servo through a significant portion of the range, which is also useful during installation. If needed, you can set the servo to a specific position anywhere within its range. It also allows up to four servos to be synchronized to the same position.
