Our meters measure impedance precisely independent of the amount of capacitance
in the measurement. When measuring human subjects this capability is
critical. The meters are of a solid-state digital design. Normally they
do not drift or require recalibration.
However, the accuracy of the meter can be confirmed in the field with the
use of a test plug. The test plug simulates the bioimpedance of the human
body. The plug can be obtained by contacting Technical
Support.
To use the test plug:
|
1. |
Remove the sensor cables from the connector at the
back of the analyzer.
|
|
2. |
Insert the test plug into the connector on the back
of the analyzer.
|
|
3. |
Turn the analyzer on.
|
|
4. |
Press the TEST key twice.
|
|
5. |
When the results are displayed press the PHASE key.
Note the resistance and reactance values. Results should compare
with the value of the test plug.
|
|
6. |
Repeat steps (4) and (5) above to confirm results. |
If the readings are outside of the range printed on the plug, the meter
requires recalibration. If you have any questions please contact Technical
Support. |
