Introduction

JJF1002 "national verification procedures write rules", JJF1001 "common measurement terms and definitions" JJF1059 "Evaluation and Expression of Uncertainty in Measurement" together constitute the support of the protocol development of the basic series specification. The regulations are based on the actual use of the technical requirements. This procedure was first formulated. Comprehensive calibration device verification procedures railroad track signal test equipment

1 Scope

The order applies to the first railway track signal integrated test equipment calibration device (hereinafter referred to as integrated calibration device) Second test, verification and subsequent use of checks.

2 Overview

Comprehensive calibration device is mainly used in railway track signal line test equipment test and calibration. Its main functions are. Single-frequency output signal frequency, voltage and current; frequency shift signal (including the center frequency of 550Hz, 650Hz, 750Hz, 850Hz frequency shift of the signal, ZPW-2000, UM71, WG-21A, etc.) frequency, voltage, Stream; 25Hz, 50Hz voltage phase sensitive track signal phase; voltage ac counting track signals, time intervals, etc. Standard signal, standard compensation capacitor and impedance.
