21,000 samples per second, and of collecting up to 100,000 samples in its internal memory. TriLog is very easy to use because all of its functions are broken down into only four buttons. In addition, when a sensor is plugged in, the TriLog automatically recognizes the type of sensor it is, and will record the data with the appropriate units. -
Page 9: Chapter 1 Trilog
Chapter 1 TriLog This section will focus on the TriLog’s data collection device: The data logger. The section includes: • How to operate the TriLog’s keypad, • How to set up TriLog • How to connect TriLog to your PC. -
Page 10: External Connections
Normally, all four sockets can be used simultaneously. To connect a sensor to the TriLog use one of the sensor cables. Plug the stereo plug into the data logger, and the mini-din plug into the sensor - arrow facing down. -
Page 11: Battery
Battery TriLog is equipped with a 2.4V/850mAh NiMH rechargeable battery. Before you start working with TriLog for the first time, charge the unit for 10 to 12 hours while it is turned off. If the data logger’s main battery runs out, the internal 3V Lithium battery backs up the memory, so no data will be lost. -
Page 12: Stand-Alone Operation
1.2. Stand-Alone Operation One way to program the TriLog is to use the keypad and screen (The other way is to use MultiLab – see page 66, or ImagiProbe – see page 24). The keypad allows us to set all the parameters for data collection, while the LCD screen displays the setting values. -
Page 13: Sensors
Plug in the sensors Start with the first input on the right (see on page 10). If TriLog is in Auto ID mode (the default mode) it will identify the sensors you’ve plugged in and display the sensor’s name. -
Page 14: Working With The Trilog Keypad
The LCD screen will display: Logging At rates of up to 10 samples per second TriLog displays the recorded data values, the number of the last recorded data sample, and the total number of samples. Use the RATE button to scroll through the different sensor’s data and the number of samples. -
Page 15: The Display
The internal clock and calendar is kept updated even when the TriLog is turned off, but it will be erased if the 2.4V battery is dead. It will be updated the next time TriLog will be connected to a computer or a Palm. - Page 16 In the Continuous mode, TriLog does not save data, and can continue logging indefinitely. If TriLog is connected to the PC and the MultiLab software is running, the data is automatically transferred to the computer and displayed in a real time graph.

Page 19: Ph Temperature Compensation
1.3.3. pH Temperature Compensation To compensate a pH sensor for temperature changes, plug the temperature sensor into Input 1, and the pH sensor in Input 2. TriLog will then display the compensated pH value. 1.3.4. MultiLab Sensor Calibration The sensors can also be calibrated using the Calibrate Sensors option in MultiLab’s Logger menu. -
