Page 5: About This Manual
Please read these carefully. NOTES and TIPS contain helpful information. Fig. 1—The Biological Signals Amplifier has four modules. INTRODUCTION This amplifier system and the sensors associated with it are designed to detect and amplify perfusate pressures, temperature and ECG signals or surface potentials from isolated perfused heart (Langendorff) and working heart (Neely) preparations. -

10mmHg or 100mmHg. Turn the 4-way program switch to either 10(mmHg) or 100(mmHg) depending on the range of pressures being recorded. The voltage change seen on the pressure recording channel should be 100mVDC for 10mmHg and 1VDC for 100mmHG. World Precision Instruments... -
Page 9: Calibrating The Pressure Sensor To Hg Module
Biological Signals Amplifier NOTE: If the recorded output signals for the 10mmHg and 100mmHg settings are not 100mVDC and 1VDC respectively, recalibrate the pressure sensor to the HG1 module using the directions provided below. Once the calibration of the sensor and amplifier have been verified, prepare to attach the pressure sensor to the cannula or catheter. -

Biological Signals Amplifier Calibrating the Temperature Sensor to the TH Module In an insulated container, prepare 2–3L of water or fluid at about 20ºC. In a second insulated container prepare 2–3L of water at a higher temperature, about 40ºC. Put a precision thermometer (0.1ºC) through the lid of each insulated container so that the bulb of the thermometer is in the middle of the container. -

[I (1), II (2), III (3)] to the analog inputs on the data recorder that are needed. TIP: If only one pair of electrodes are needed to record a surface potential from heart muscle, then only one of the leads (I, II, or III) needs to be connected to the data recorder. World Precision Instruments... - Page 13 Biological Signals Amplifier Turn the 3-way program switch on the front panel of ECG amplifier to GND. Turn on the amplifier. A signal of zero (0) volts is sent by the amplifier to the data recorder. If necessary, set the baseline of the recording channel to zero (0) using the controls of the data recording system.
