LOG-HC2-RO1 LOG-HC2-P1 Instructions Operating Instructions
The logger is a miniaturised universal datalogger for measuring and recording different physical measurement parameters. For further information, see data sheets. The Logger PC program enables users to customise the way in which the logger measures and records data according to their requirements. The integrated clock (RTC) allows data from as many loggers as required to be synchronised and merged into a single data record.
The storage properties of the logger are determined using the Setup program*. Control of measurement parameter storage can be either time activated, value activated or by pushing the push button. See also chapter „Logger display / Logger operation“ on page 12. *Setup is an LOG PC program (see below).
When the logger is turned off 1 the display cannot be activated using the T1 or T2 keys. The display and keys are activated by connecting the logger to a USB port or charger 2. The display is operated using keys T1 and T2 (see the diagram "Display and operation").

Basic settings This page describes the most commonly used settings – the Basic settings. Information on further settings can be found on the following pages. Name of the logger ->33 Currently no data is being recorded (inactive) (active: data recording in progress) Setup • Complete the preparations (->33). • Start Setup (Setup symbol). • Edit the Basic settings according to your requirements. • Transfer the new configuration and the start conditions to the logger with Write basic settings.
Prediction With each click on Prediction (Basic settings) the program generates an approximate prediction using the selected basic settings. Note: The Limit settings are not taken into account here.
Reducing the volume of data When making extensive recordings it is recommended that all sensors that are not required be “turned off”. This prevents unrequired measurement parameters from being saved. Conditional recording of measurement parameters (limits) If for example, you require only to record temperatures above 5°C and less than 20 °C, use the following procedure: • Activate Limits active 1 and the corresponding temperature sensor 2. • The Limits tab opens.
LED behaviour The behaviour of the blue LED is defined via Setup > Basic settings.
