The new P.A.M. (Pressure Application Measurement) The operator simply wears a special force sensor on device from Ugo Basile is a novel, easy-to-use tool for his or her thumb and measures the force which elicits measuring mechanical pain threshold in experimental the animal response (normally, limb withdrawal).

P.A.M. PRESSURE APPLICATION MEASUREMENT 3 8 5 0 0 Cat. GENERAL PAM is designed to measure and record the forces exerted on a subject’s joint, paw or muscle. Its fields of application include: Arthritis Chronic and Acute Pain Allodynia and Hyperalgesia Phenotyping and Functional Genomics PAM is battery-operated and is charged via the included USB cable.
The rate of application of the force is decided by the operator and the PAM includes software tools that help the operator in consistently applying the force at the desired rate. The results of, typically, several thousand tests may be stored in PAM for transfer to a PC when convenient.
16 hours. When PAM is switched OFF, it goes into a standby mode in which it takes almost no current from the battery although it still updates its internal calendar clock. PAM is switched ON by pressing the ON/OFF button.
Each transducer contains a memory chip which identifies the type of transducer and its specific characteristics including all relevant factory calibration information. This feature allows PAM to adjust automatically to each transducer and ensures that transducers and PAM instruments may be interchanged without the need for routine re-calibration.

3 hours. 3.4 Connections Plug one of the force transducers and the foot pedal into the PAM electronic unit, by using the connectors located in the back panel. 3.5 Installing the PAM Software The software provided with PAM should be installed on a suitable Windows PC, running Windows Vista or XP.
4.1 First time operation After charging PAM for at least 1 hour, plug in the large transducer and turn the instrument ON by pressing the ON/OFF button. Once the introduction is completed, the initial menu will appear as below.

Test 1 Exit Test Check that no force is being applied to the connected transducer and then press Test. PAM checks the transducer zero and then displays: Measure Peak Force Apply the force NOW Apply gentle force to the transducer. The display changes to typically.

If the result is accepted, the results are stored in PAM’s memory and the user is given the option to finish making measurements or do another test.
4.4.4 Transfer Data to PC This option allows data stored in PAM’s memory to be transferred to a PC. It requires that PAM is connected to a PC via the USB cable supplied and that the PC is running appropriate software such as the PAM PC software provided with the instrument. Detailed operation is covered later in this manual under PC Software.
Pressing Set config allows the user to adjust a number of configuration settings in PAM. These include options related to the measurement process such as whether the measurement is ended automatically by removing the applied force or manually by pressing the foot trigger switch but also covers more general settings such as the brightness of the display and the period of inactivity before PAM will switch itself off.

Adjust the period of inactivity after which the display dims (never) Adjust the target force rate (120gf/s) Set current date and time – this can be set by the PAM control unit or by the PC Return to the Main Menu (by pressing Exit).
At this time, PAM may still be used but the USB lead should be connected to an active PC or a USB power adapter to charge the battery as soon as possible. If the battery is so low that PAM cannot operate, then the instrument switches OFF immediately.
Whether the operator should be asked to indicate Left or Right limb or not (default). Whether PAM should use Subject Numbers or not (default). Whether PAM should use the applied force ratemeter during tests or display live force and time in text (default).
5.6 Updating the PAM firmware The hardware used in PAM is very flexible and many of PAM’s features are determined by its internal software program or firmware, as it is often called. When improvements and additions are made to the firmware, existing users may update easily to the new version.
PAM Software program from the Windows Start Menu. The following screen will appear If the PAM button is not showing then the USB interface in PAM has not been detected, the PAM is therefore not connected and the user should click Exit, disconnect the USB lead for a few seconds then re-connect the USB lead and run the PAM PC program again.
On the start screen above, click Use PAM Device and a box should appear with Waiting for PAM. The traffic lights should all be grey. If PAM is connected, during tests, to a PC which is Waiting for PAM, the PC will display the force curve while the force is applied, as shown below.

38500 Instruction Manual (Rev.1) 6.3 Downloading data from PAM All Data Downloading is controlled by the PAM Controller, which can be thought of as the brain of the instrument. First, ensure that the PAM controller is properly connected to the PC, and that the software is working properly.
Use the drive, folder and file selection boxes to select the required data file. If necessary, refer to section 7.2 for an explanation of the automatic file naming system used by PAM PC. The display of the first test stored in a typical downloaded file is shown below.

Use the Previous and Next buttons to scroll through all saved tests until the software shows the required test. If the left or the right mouse button is clicked in the display area of the graph, the vertical white cursor line is displayed and the force and time relating to the dark cursor (corresponding to the peak) position are displayed below the graph.

The data in the Excel file consists of columns for measurement number, peak force and peak position, filled with the values for each of the tests downloaded.
