INTRODUCTION

The PTR (Printing Temperature Recorder) is a hand held temperature measuring
device that prints and logs temperature readings.

The PTR measures temperature across the range of -328 to 2501°F (-200 to 1372°C),
with a resolution 0.1°C above 1999.9°F/C.

When the PTR is fully charged, up to 500 prints can be achieved. Up to 8000 readings
can be stored in memory.

PROBES

The PTR can be used with the standard range of ThermoWorks thermocouple
probes fitted with a miniature thermocouple plug. The probes are connected via the
4 miniature thermocouple sockets at the top of the instrument.

FUNCTIONS

The PTR control panel consists of five buttons:

ON/OFF - Switches the PTR On/Off.

INPUT - Changes selected input.

LIMITS/START STOP - Displays High or Low Limit in ‘on demand’ mode. Starts and
stops logging in ‘log’ and ‘summary’ modes

FEED - Feeds the paper.

PRINT - Takes a reading, prints a ticket and logs the reading, date and time in memory.

DISPLAY

The display consists of a 12 character alphanumeric section and a four and a half
digit temperature section. A low battery is indicated with 'Lo Bat'.
