4. For respiration, set the "LEAD" switch to "II/RL-LL" and the "IMPEDANCE"
switch to "500". The first respiration step is a reference step. Do not adjust it.
Record it and add it to the value called for in the remaining respiration steps, or
offset the DMM to zero.
5. For blood pressure, connect the blood pressure calibration cable to the 10-volt
supply and DMM as follows:
Cable Wire Connection
GRY +SUPPLY
GRN -SUPPLY
BLK +DMM
RED -DMM
6. Set the "SENSITIVITY" switch to "40". Set the supply to +10 V ±10 mV. The
calibration steps call for +10 V or -10 V or 0 V. To get the -10 V exciter, reverse
the connections to the supply. To get 0 V exciter, remove the connections from
the supply.
7. To calibrate temperature, use the temperature calibration cable. Set the
"CARDIAC OUTPUT/ VAR TEMP" switch to "VAR TEMP". Following are the
three different cable and switch settings used in the calibration steps:
Cal Steps Cable Colors Probe Switch DMM Current
T1 GRN-RED
700
10-100
µA
T2 GRY-RED
700
1-10
µA
400 BLK-RED
400
10-100
µA
The chart above also indicates the DMM output current that must be used.
Note
Most meters use 100 µA for the 20 k
e
range and 10 µA for the 100 k
e
range.
8. To calibrate cardiac output, use the cardiac output cable. Set the "CARDIAC
OUTPUT/VAR TEMP" switch to "CARDIAC OUTPUT".
9. Set the DMM to measure resistance using 10 µA. Connect the black cable lead to
the "+DMM" jack and the red cable lead to the "-DMM" jack.
10. When the last step is completed, the calibration constants are automatically
stored in the medSim 300B and a long beep indicates that the calibration
procedure is completed. Now you may reassemble the unit.
