Functional Checkout Procedure: Strain Gauge Transducer Test
Strain Gauge Transducer Test
1. Inspect a Model 116/118/120 strain gauge as follows:
îš‹ Unscrew the plastic dome from the transducer and check for any cracks or
contaminants on the transducer.
îš‹ Visibly assess the condition of the cable, strain relief, and the connector
pins.
2. Connect the strain gauge to the
UA input receptacle on the front panel of the 120
Series Monitor. Verify the following on the monitor:
îš‹ The UA value may read negative numbers indicating baseline pressure is
off scale. In this case, the recorder prints the message
BASELINE
PRESSURE OFF SCALE
on the center margin of the strip chart paper.
îš‹ The UA mode is IUP for intrauterine pressure.
îš‹ The recorder prints the message IUP on the center margin of the strip chart
paper after approximately 20 seconds.
3. Depress the monitor’s
UA Reference pushbutton and verify the following on
the monitor:
îš‹ The UA value is 0 mmHg.
îš‹ The recorder prints a continuous line at 0 mmHg on the strip chart paper.
îš‹ The recorder prints the message UA REF on the bottom two lines of the top
grid of the strip chart paper.
4. Apply gentle pressure on the strain gauge diaphragm and verify that the display
and recorder respond to the input. Increasing force should produce an
increasing value and vice versa.
5. Disconnect the strain gauge from the front panel of the monitor. Verify the
following on the monitor:
îš‹ The UA value and mode are both blank.
îš‹ The recorder stops printing the uterine activity trace.
