SYN5301 Type Time Verification device

SYN5301 type Time Verification Device

Fixture overview

Our fixture can be placed horizontally measured stopwatch, but also vertical measurement of the stopwatch, and other manufacturers of fixtures can only be measured horizontally, if you want to vertical measurement to rely on the wall or other objects to test, so that the detected data will have a certain deviation, and their fixture rough, 2, other manufacturers of fixtures can only test 1 blocks, While our fixture can measure multiple stopwatch at the same time, this will greatly save time, moreover, our fixture work more delicate, more in line with the stopwatch verification procedures.

Product introduction

The SYN5301 type time verification device is a high precision time calibrator. This equipment is based on the requirements of jjg237-2010 "stopwatch verification procedures" of a multifunctional, comprehensive time verification automatic testing device for the verification of mechanical stopwatch, electronic stopwatch, pointer-type electric stopwatch, digital electric stopwatch, digital millisecond meter, and various timers, etc. Measured by measuring the standard time interval signal, the instrument is measured by measuring the measured value of the standard time interval signal, so as to obtain the measurement error of the instrument, to achieve the purpose of verification, suitable for various types of stopwatch of the value of transmission, can establish a stopwatch calibration standard device, to carry out time-class instruments for verification/calibration.

Product Features

classification of mechanical stopwatch

1 Press the second hand to beat the amount divided into: 1% (0.01) seconds, One-fiftieth (0.02) seconds, One-tenth (0.1) seconds and one-fifth (0.2) seconds four kinds. 2 The number of seconds is divided into two types: application and double needle. The two-pin stopwatch secondary seconds stop should not be related to the primary hand, and after the stopwatch is stopped, the secondary second hand can not be reversed to 0 and coincide with the main second hand.

3 According to the second hand action situation is divided into: simple action and comprehensive action two.  The former must be returned to 0 after the pointer has stopped, and the latter can start moving at any position where the pointer stops. 4 According to the minute hand action situation is divided into: instantaneous action and semi-instantaneous action two kinds.  The minute hand of the former rotates continuously with the second's stroke, and the latter only beats once at a certain value. 5 According to the structure is divided into: continuous action and discontinuous action of two. The former does not interrupt the rotation of the balance wheel when the second hand starts and stops, and the second hand starts and stops as a result of the wheel's push or braking action. In addition to this, some stopwatch dials can be rotated, the dial can be rotated to 0.

Part of the verification procedures:

First, technical requirements

The 1-second table is divided into one and tertiary according to the accuracy level, and its accuracy index

(The average correction value C and the allowable maximum deviation for each of the corresponding locations allowed) should not be greater than the values listed in table 1.

2 seconds after the watch is fully wound, the duration should be no less than the schedule.

The 3 second table must have the manufacturer's name and number.

Ii. Conditions of verification

4-Ring condition

4.1 Ambient temperature: 20±5℃.

4.2 Relative Humidity: 80% or less.

The 4.3-second table must be placed in the verification environment for more than one hour before verification.

5 Standard equipment

Any of the following standard equipment may be used for verification purposes (but no mechanical stopwatch is allowed for the calibration of mechanical stopwatch).

5.1 Second meter calibration device. The basic error does not exceed ±10ms.

5.2 Standard precision clocks. The daily difference does not exceed ±4s.

5.3 Quartz clock. The second hand beats at 1/2s or 1s, and can hear a clear seconds beat, and the accuracy of the crystal oscillator is better than 2x10-5.

6 check interval is the second dial and the full value of the sub-scale (such as the use of the stopwatch has special requirements, can be negotiated with the verification unit to resolve).

7 verification shall be carried out within the specified clockwork effective working time
