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 DATA key. Enter data representative of an actual subject. |
| 5. | Press the TEST key twice. |
| 6. | When the results are displayed press the OHMS key. Note the resistance value. Results should compare with the value of the test plug. |
| 7. | Repeat steps 5 and 6 above to confirm results. |
If the readings are outside of the range printed on the plug, then the meter requires recalibration. If you have any questions please contact Technical Support.
