Measurement mode
• Surface measurement for the 4-point Wenner probe measurement.
• Bulk measurement for working with the bulk resistivity accessory.
Contact Spacing
• Default spacing – either 38mm or 50mm depending on Resipod model.
• Custom spacing – with the variable spacing probe accessory this may be anywhere between
40mm and 70mm. It is also possible to set a spacing beyond this range, for use with customized
extension cables.
Geometric Correction Factor
• Flat – Default setting, used for measuring on site and also for use with the AASHTO T 358 standard.
• Cylinder – Set the length and diameter of the cylinder under test.
The surface measurement correction factor (k) is calculated according to the latest research for
surface resistivity of hardened cylinders.

d/a (d/a)²
d = diameter of the cylinder (mm), a = probe spacing (mm), L = length of the cylinder (mm)
Formula valid for: d/a 4 and L/a 5 (e.g. for a 200mm cylinder, the maximum probe spacing
allowed is 40mm)
The bulk measurement correction factor is calculated according to the method described in
chapter 5.1.:
e.g. k = A/L = (π x 5

) / 20 = 3.927
• Prism – Used for cubes and prisms. No correction factor is implemented to date for the surface
measurement. The bulk measurement is calculated according to the method described in chap-
ter 5.1.
• Custom Correction Factor – For user defined correction factors, select this option and enter the
correction value directly. If not selected, the value shown here shows the calculated correction
factor (k) based on the options selected above.
Downloading loading the Correction Factor to Resipod
• Complete the action by pressing OK. A warning will be shown to indicate that all measurements
currently saved on the Resipod will be deleted.
