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.

PTR OPERATION SWITCHING THE PTR ON OR OFF The 'On/Off' button switches the PTR on or off. 'Switch off' will be displayed for two seconds before shut down is complete. The unit cannot be switched off using the 'On/Off' button during a log. The log must be stopped first. CHANGING INPUT To scroll through the four inputs, press the 'Input' button. The selected input will be displayed on the screen. Inputs change in a continuous loop. Up to four inputs can be selected using the PC software.
STOP button once. To stop logging, press the START STOP button, 'Stop Log?' will be displayed. Press the START STOP button again to confirm the log is to be stopped. The log MUST be stopped before the instrument can be switched off. 'LOG' MODE The print button is disabled and the printing is automatically timed at set intervals selected by the user. If there is no paper loaded or printer cover is open, 'Paper out' will be displayed, but the reading will still be stored.
BATTERIES The PTR is fitted with a 3 cell rechargeable 3.6V NiMh battery pack. It is NOT user replaceable. Please return to ThermoWorks for battery replacement. When the PTR power is low, the 'Lo Bat' segment of the LCD is lit. Print and feed operations are inhibited when 'Lo Bat' is indicated. Pressing the 'Print' or 'Feed' buttons will result in 'Recharge' being displayed for a short time in the display.
PAPER LOADING PROCEDURE To reload the printer with a new paper roll, follow the steps below: 1. Un-clip the printer cover handle (Fig 1). 2. Pull the printer cover handle until the cover un-clips. To avoid damage to the handle do not use excessive force (Fig 2). 3. Lift the lid until completely open (Fig 3). 4. Remove any existing paper or the plastic tube from the previous roll. The easiest way to do that is to turn the PTR upside down, so the printer contents fall out (Fig 4). 5.
