Description
The No.1900 timegrapher is a high-precision instrument used for multiple tests related to mechanical watches. It’s an essential tool for watch manufacturers and watch technicians alike.
Features
This timegrapher displays the frequency diagram of the watch on its LCD screen. Moreover, it automatically adjusts the optimal signal level based on the watch being tested. This device automatically calculates and displays rate deviation, amplitude, beat error in real-time data. It can select “+/-99.9s/d” as result display, significantly enhancing the accuracy of rate deviation by up to 0.1s/d.
One of the key benefits of this timegrapher is its adaptability. It can automatically respond to conventional beats and manually select for special beats. Its sampling periods can be adjusted to 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds – the average value within this period is identified as the precise value of the watch. The device offers six adjustable testing positions and its built in speaker can either play simulation sound or be muted.
Specifications
The timegrapher offers multiple plug options including EU, US, and AU plugs. It is made primarily of durable ABS material. Its color scheme is comprised of combination of grey and black. This product is capable of measuring rate deviation, amplitude, beat error of mechanical watches, and record a diagram of the beat noise.
