PicoLog 1000 Series User's Guide 1 Introduction 1.1 Overview 1 The PicoLog 1000 Series PC Data Loggers are mediumspeed, multichannel voltage-input devices for sampling analog data using a PC. This manual describes the physical properties of the loggers.
2 1.2 Introduction Safety warning We strongly recommend that you read the general safety information below before using your product for the first time. If the equipment is not used in the manner specified, then the protection provided may be impaired. This could result in damage to your computer and injury to yourself or others. Maximum input range The inputs of the PicoLog 1000 Series loggers are protected against overvoltages up to ±30 V.

4 1.4 Introduction Accessories The following items are supplied in all packages: Standard items Part no. PicoLog 1000 Series PC Data Logger PP543 (PicoLog 1012) PP544 (PicoLog 1216) MI106 DI025 DO112 USB cable Software and Reference CD-ROM USB Installation Guide The following additional items are supplied in some packages (see our website for details): Additional items Part no.
PicoLog 1000 Series User's Guide 1.6 5 Connecting the logger Before you connect your logger, you must install the software supplied on the CD. To connect the PicoLog logger, plug the cable provided into any available USB port on your PC. I/O connector: for the pin-numbering of the I/O connector, see I/O connector pins 9 . The Pico PP545 Small Terminal Board is specially designed to connect to this socket to allow you to make connections to individual wires easily without soldering.
6 1.8 Introduction Example circuit (voltage) This is how to connect a simple voltage source to the Data Logger: The components of the circuit are as follows: V Battery R 1 MW C1 Channel 1 GND Ground Any cell, battery or transducer with a voltage output in the range 0 V to +2.5 V. The input resistance of the PicoLog Data Logger. You do not have access to this resistor, but you may need to know its value when designing your circuit. The C1 pin on the Data Logger.
PicoLog 1000 Series User's Guide 1.9 7 Example circuit (light) Here is an example of a sensor circuit that you could connect to the logger. The components of the circuit are as follows: R1 ORP12 R2 100 kW R3 1 MW C1 Channel 1 PO +2.5 V GND Ground A light-dependent resistor of type ORP12 or similar. In the dark this acts like a fixed resistor with a high value of 1 MW or more, but when exposed to light its resistance drops in proportion to the brightness of the light, down to several kW.

10 Product information The I/O connector pins are numbered as follows: 2.3 USB ADC-11 compatibility mode The PicoLog 1000 Series data loggers may be used as replacements for the USB ADC11, an 11-channel data logger previously available from Pico Technology. The 1000 Series units have all the functions of the USB ADC-11 and some extra functions, such as extra digital outputs 9 , a PWM output 9 and a sensor power output. They also have a faster USB interface and more advanced driver software.
PicoLog 1000 Series User's Guide 3 11 Glossary Accuracy. The closeness between measured values and true values. This is more usually expressed as the error, as a percentage of full scale, between the measured value and the true value. ADC. Analog to Digital Converter. An ADC samples analog signals and converts them to digital data for storage and processing. It is an essential component of a data logger. Analog bandwidth.
