    If this is a new installation, it is more likely that you plugged the logger into the USB port before loading the PicoLog software in which case Windows will try to load a generic driver which will not work. It will not be overwritten by the correct driver until the wrong driver has been uninstalled.
  • Page 4 Install for other devices. This will load all the other drivers for all other Pico loggers and allow you to select them if you need to use them with PicoLog at a later date. That should sort things out.

  • Page 5: Finding The Picolog Software Version

    PicoLog Self-Help Guide Click OK and PicoLog will start to install in the usual way. At the end, whether the software has installed properly or not, there will be an Install.log file in the C:\Temp directory. Please email that file to support@picotech.com and we can then see what has gone wrong with the installation.

    8. When you start PicoLog, you get Player and not Recorder If, when running PicoLog, you minimise the Recorder window, it will shrink to a small PL logo in the bottom right of the toolbar: Figure 2 - PicoLog icon in System Tray After a short while, the icon may disappear.

    PicoLog. Here are example instructions how to use, for instance, five TC-08 loggers at a time:- 1. Plug five TC-08s in via a powered USB hub. Start up PicoLog. Select File, then New Settings. In the Recording dialog box, tick the box for Use multiple converters.
  • Page 9 PicoLog Self-Help Guide This will take you to the Converter Details box where you select TC-08 (USB). PicoLog should find all the data loggers: 3. Click on the first one shown in the USB Devices box and click OK. You will be returned to the Converters dialog where you click Add again.
  • Page 10 Only 20 channels can be displayed at any one time in Graph view and 16 channels in Spreadsheet view. (Viewing more than 20/16 channels at a time would be difficult to interpret.) AR346-1 © Copyright 2014 Pico Technology Ltd. 10/34...
  • Page 11 You can then at any time call up these groups for viewing, in quick succession. Please see page 37 of the PicoLog manual (issue 5) for how to set up a group (please refer to the Related Documents section).

    The User’s Guide then provides information on how to start the PicoLog Recorder instances using the Windows command line interface. Alternatively, a batch file can be created allowing a user to double-click the file and start the two instances of PicoLog Recorder.

  • Page 13: Remote Data Logging In Picolog

    Taken from page 19 of the PicoLog User’s Guide (see Related Documents): The PicoLog IP socket facility is used to take measurements on one or more computers and record the data on another computer. The measurements are taken by PicoLog on the Server.

    (whatever the number of channels). If you wish to log for longer periods you need to set PicoLog to Repeat Immediately at the end of a run. A new file will be started with an auto-incremented file name. For ease of use, do not use the maximum file size, but choose a convenient number of samples that gives a reasonable logging time per file.

  • Page 15: Picolog Frequency Measurement

    Set the scan time to 100 000 µs, which will give you a frequency range of 20 Hz to 11.626 kHz. • Using Options and then Scaling you can get PicoLog to display in RPM, not frequency (click Help for instructions). Back in Edit PicoLog1216 Measurement, click OK.

    Windows operating system. Plug your TC-08 into the USB adapter and run PicoLog. When asked for the COM port to use, enter the COM port allocated in Device Manager. If you use a different USB port next time, please be aware that the COM port number may change.
  • Page 17 You just need to set the scaling for the channel in question. We will illustrate how to scale Temperature for each channel. Start PicoLog and set up your sample rates as required. When you get to setting up each channel, click on Edit, then click on Options.
  • Page 18 Duplication of parameter formatting will cause a crash! When all channels are done, save a settings (.pls) file and next time, when you want to reapply the same calibration to a logging session, just start PicoLog by double-clicking the settings file instead of the PicoLog icon.
  • Page 19 4 mA and 30 psi at 20 mA, you would set up a lookup table to equate 9.5 (mV) to 0 (psi) and 47.5 (mV) to 30 (psi). 1. Start PicoLog and set-up your sample rates as required. When you get to setting up channel 1 (Edit TC-08 channel), type psi as the Name and mV as the thermocouple.

    15.2 Device-specific – PicoLog 1012 and 1216 Sampling at 1 ms in PicoLog with the PicoLog 1012 and 1216 If you find that you any only log at about 20 to 50 ms sampling rates, you are probably running in "Real Time Continuous" mode.
  • Page 21 In this mode you can sample on all 16 channels, getting one reading from each in a 1 ms period. AC voltage, frequency and dB readings will not be offered, though. Triggering in PicoLog The PicoLog 1012 and 1216 data loggers can trigger from any of the available input channels, but only in "Block" mode. Sampling modes PicoLog 1000 Series loggers can run in various sampling modes.
  • Page 22 480 mV to 2400 mV. The resistor is best placed in parallel with the input terminals of the PicoLog 1012 (from the channel input pin to ground). The 0 V terminal of the +12 V to 24 V sensor supply is connected also to the ground of the 1012.
  • Page 23 C1 and 2.5. If you can only get a surface-mount 39 kΩ resistor, you can mount it in the R33 position on the terminal board as shown in page 4 of the PicoLog 1000 Small Terminal Board User’s Guide (see Related Documents).
  • Page 24 (100 x 1,000) / (100 + 1,000) kΩ = 90.91 kΩ (@25 °C) The +2.5 V sensor supply of the PicoLog 1012 is fed through the 47 kΩ resistor to the thermistor wired across the input channel and @25 °C the voltage at their junction will (2.5 x 90.91) / (90.91 + 47) volts = 1.648 V.
  • Page 25 6. For Scaling method, select Use scaling from file and click File. 7. Navigate to where you have saved the scaling file below, as 100k thermistor.scl. 8. Open the file. Click OK several times to get back to the main PicoLog window. You should be reading temperature on channel 1.

    It is possible to offset and scale a negative signal. There is a +2.5 V, 10 mA source available on pin 17 of the PicoLog. To start with, you will need to add resistors to the terminal board exactly as described in the PicoLog 1000 Small Terminal Board User’s Guide (see Related Documents).
  • Page 27 If the sensor is not powered-up, the reading will be about –1.2 bar as that is the equivalent reading for zero mA. (0 bar = 4 mA). Look through the PicoLog manual for information on using PicoLog or click on the Help button at any stage in PicoLog.
  • Page 28 Below is a series of steps describing how to set-up channel 1 for temperature measurement from 60 °C to 110 °C. 1. Start PicoLog and set-up your sample rates as required. 2. When you get to setting up Channel 1 (ADC-24 Channels), highlight Channel 1 and click Edit.

  • Page 29: Device-Specific - Pt-104

    It is possible to set the sample rate of PicoLog faster than that so it can detect a change in reading with a worst-case delay of one sample period.

    PicoLog. Below is an example file Ext Volts.dds which you can use as a start. If you put a 3.3 kΩ resistor between pins 2 and 3, that will tell PicoLog to use [Scale1], which will then give you voltage readings between 0 V and 2.5 V on any Ext Input that is connected.

    The PicoScope 2203/3A/4/4A/5/5A have relays that switch between the high and low voltage ranges on each channel. When running in PicoLog, the input signal is fed through from one input connector to both channel’s A to D converters in parallel to get twice the bandwidth.
  • Page 32 Logging a 4-20mA sensor using a PicoScope 2203, 2204 or 2205 Below is a description of how to use an 8-bit PicoScope 2203, but the 10-bit PicoLog 1012 or 12-bit PicoLog 1216 would give more resolution, if required.
