Maintenance and calibration

About external dimensions

Although the external dimensions are 

79 mm

φ

 × 110 mm, the conductive pad 

in contact with the object to be measured is 

63.5 mm

φ

 and conforms to the standard.

On the resistance of the electrode device

RCJS-5-1 stipulates that "the inter-point r

esistance between two probes must have 

sufficient conductivity so that it is lower 

than 10

3

 

Ω

".

For our products, the resistance per 

electrode (between the cord jack and the 

conductive pad) is 400 

Ω

 or less, and the 

resistance of the circuit as shown in the 

figure is 800 

Ω

 or less.

About weight

Weight 2.3 kg (1 piece) conforms to the 

standard 2.5 kg ± 0.25 kg.

  When the electrode becomes dirty please wipe gently with alcohol etc.

 

Do not use thinners, benzine, etc.

  We also have calibration certificate attached (F-109-TA, F-109-1-TA). 

 

Please re-calibrate after use for a certain period through our purchase store.
