1. GENERAL DESCRIPTION

1.1. INTRODUCTION

This manual describes the physical, mechanical and electrical features and functions of the TL-3724
Combined Engine Instrument.

1.2. EQUIPMENT DESCRIPTION

The TL-3724 is a complete engine monitor for measuring all quantities of an engine.
The TL-3724 facilitates seeking the cause of an engine default or damage, with use of the SchecK®
method for storing the measured values into the memory.
The TL-3724 checks all measured values at two levels - for a warning and an alarm limit signalization.
When the alarm warning has been activated, the instrument will display a Service message after the next
turn-on to inform the user on the exceeded some value.
The instrument incorporates a 2,000-line long-term memory and SchecK memory (see page 5-1) for
storing the measured values at 0.1 to 60 second sample rate.
The TL-3724 incorporates a Memory / Info button for displaying the maximum measured values and
other information.
It is possible to download the measured values from the instrument via the serial cable RS-232c into your
PC.

The placement of the values on the display, as well as setting the quantity you want to
show, can be changed at any time with use of the Windows program delivered with the
instrument.

The producer of the engine instrument and its distributor reserve the right not to announce
the correct code as this code helps to decide whether the guarantee can be applied.
