INTRODUCTION

The TI21 Test Meter (TTM) has been designed to measure voltages at specific TI and ASTER/SF frequencies. It enables readings of track circuit parameters to be taken without corruption from other track circuits or interference at non-TI frequencies, e.g . 50/ 60Hz. It is intended for use as an aid to fault finding with TI and ASTER/SF track circuits . For normal setting -up procedures please refer to the appropriate Manual/Code of Practice/Handbook

The TTM can also be used to measure track circuit current in the running rails when used in conjuction with a Rocoil Rail Current Transducer (RCT), please refer to the RCT operating instructions (note that an RCT is not supplied with the meter). The meter is supplied with a carrying case and leads.
