B High Cal/SpanGas Adjust
A High Cal/Span Gas should only be preformed after a successful Low Cal/ZeroCal has been completed.
Press the SELECT switch, that moves the cursor one digit to the right when the last digit is accepted the display will move
to " HiCal xx " gas calibration. xx = the level of gas to be used for calibration. The mV reading is shown in the upper right
hand corner of the display.
Apply calibration gas to sensor. See Figure 7. After about 1 minute and mV reading has stabilized.
Press the SELECT switch, that moves the cursor one digit to the right, when the last digit is accepted and the calibration is
successful the display will momentarily show Cal OK then slope and off set readings, before returning to the Calibration
Menu
Repeat above steps for each channel to be calibrated.
To continue on too next section Press the
OPTION switch.
Press OPTION switch until “Exit maint menu” appears and then press SELECT switch to return the instrument to the
Operational Display
5.5 Flow Control Orifice
A 0.0225-inch diameter orifice is used to set the flow rate. In well-maintained medical air systems, this orifice should not clog.
However, if difficulty is experienced in maintaining flow rate examine this orifice; replace it if necessary.
Orifice location will depend on instrument sensor configuration.
