Service menu for Pressure Module, M-P or E-P, and
Pressure Temperature Module, M-PT or E-PT.
Calibrations: see section “P/PT Calibrations”.
Temp Test activates the automatic temperature test
for the temperature channels T3 and T4. 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.
Record Data: Record Data prints out the shown
service data and board information (id., serial
number, and software id.) onto the recorder.
Service Data
Gain is a coefficient to compensate gain error.
Usually the value for P3 is between 17000 and 25000
and for T3 and T4 between 13000 and 14300.
Zero indicates the offset compensation value of each
parameter in the A/D converter. Typically the values
for P3 are within ±1000 and for T3 and T4 between -
150 and +300. Calibrate if the zero and/or gain value is outside the ranges.
Cable shows ON when the corresponding cable isconnected to the front panel.
Probe shows ON when the corresponding probe is connected to the cable.
Under Value, the measured numeric values are displayed simultaneously. The pressure value is a real time
value and shown in mmHg.
Button; the front panel key function can be confirmed by pressing the key and checking that OFF turns to ON.
Temp error shows whether the calibration of the temperature was successful or not.
Protect key shows normally OFF but turns to ON when the button at the bottom of the module is pressed.
Protect mode is normally ON. It turns to OFF when Protect is switched to OFF for the temperature calibration in
Calibration Menu.
Configuration shows the chosen module configuration: BP or PT.
Timeouts is a cumulative number that indicates how many times the module has not responded to the
monitor's inquiry.
Bad checksums is also a cumulative number that indicates how many times communication from the module
to monitor has broken down.
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has
detected.
The monitor starts counting these items at power up and resets to zero at power off. The values may also be
reset when a module is attached to the monitor frame and be set to 32769 or continuous counting may be
started when the module is removed from the monitor frame.
The nonzero values do not indicate a failure, but the continuous counting (more than 5 per second) or value
32769 indicates either a serial communication failure or a module not in place. Also failures in other modules
may cause these numbers to rise or be set to 32769.
