Record Data
Record Data prints out the shown service data and board information (id, serial number and sw id)
onto the recorder module, M-REC.
Temp Test Temp Test activates the automatic temperature test for the temperature channels T1 and T2. The
result from the test is shown in the service data field.
NOTE: The Temp Test needs to be selected twice before the test starts.
Service Data field
Gain
is a coefficient to compensate gain error. Usually the values for P1 and P2 are between
17000 and 25000 and for T1 and T2 between 13000 and 14300.
Zero
indicates offset
compensation value of each parameter in A/D converter. Typically the values for P1 and P2 are
within
±
1000 and for T1 and T2 between -150 and +300. Calibrate if zero and/or gain value is
outside the ranges.
Cable
shows ON when a corresponding cable is connected to the front panel and Probe shows ON
when a corresponding probe is connected to the cable.
Under
Value the measured numeric values are displayed simultaneously. Pressure values are real
time values and shown in mmHg. Temperature values are shown in degrees Celsius.
The front panel STP keys functions are confirmed by pressing each key and observing OFF turns to
ON at
Button .
SpO
2
shows measured beat-to-beat SpO
2
value. Modpr is a modulation % that indicates AC/DC
ratio in the measured signal. Hr is a pulse rate calculated from every beat.
Cable
and Probe can be either OFF or ON, and these indicate the state PROBE OFF.
Under them there is a message field for SpO
2
. It can be OK, PULSE SEARCH, NO PROBE, PROBE
OFF, NO PULSE, ARTEFACT, POOR SIGNAL, or CHECK PROBE.
Balance between leds is adjusted by changing the intensity of red/infrared. Intensity of infrared
(
Ired int.
) is in the range of 40 to 255 and red intensity (
red int.
)is in the range of 40 to 255.
DC gain
shows the gain of DC signal adjusted by the module.
