Function: - The WEI SHI WATCH EXPERT No.1900 is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician. - The frequency diagram of the watch can be displayed in the LCD screen. - According to different watches, the instrument will automatically adjust optimal signal level during testing. - The instrument will automatically calculate the rate, amplitude, beat error, and display them by data in real time; Select “±99.9s/d” at item Rate Range for result display, can make the precision of Rate Deviation up to 0.1s/d. - For the conventional beat, the instrument can automatically response; for the special beat, can manually select. - The sampling period can selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds, and the average of corresponding period will be regard as the precise value of the watch. - Six kinds of testing position can be adjusted, and the simulation sound can be play in the speaker or mute.
Parameter Data: - Measuring possibilities: Rate deviation, amplitude, beat error of mechanical watches and diagram recording of the beat noise. - Beat numbers: The instrument can check up the normal beat numbers automatically and also can find out the uncommon beat number by manual. - Rate accuracy: the measuring range is ± 999s/d or ± 99.9s/d, resolution 1.0s/d or 0.1s/d. - Amplitude measurement: Numerical display in degrees, resolution is 1°, measuring range: 100° ~ 360° (the lift angle can affect the amplitude, range: 30° ~ 70°. Under normal circumstances, the amplitudes value does not exceed 360°.) - Measuring times period for the average numerical results: 2s, 4s, 8s, 12s, 20s, 30s, 30s, 60s. - Measuring of the Beat Error: Numerical display in milliseconds; Resolution is 0.1 milliseconds; the measuring range is 0.0 ~ 9.9 Ms. - Lift Angle: The measuring range is 30° ~ 70°; the default value is set to 52°. - Supply voltage: Single-phase AC 100V ~ 240V ± 10% two-wire. - Measure positions: 1 ~ 6 positions. - Display: Color LCD graphic monitor, 480 x 272 pixels. - Working environment: 10A„ƒ ~ 40â„A, relative humidity: 0 ~ 80% RH - Shell: Light grey plastic - Dimensions: 173×9.5×11.5 mm - Weight: 402g
