ZFM 100
Kit
ZFM 100, battery, nylon bag, operating manual.
Description
ZFM 100 is an electronic dampness indicator with a measuring process working on the principle of high frequency measurement. The instrument is used for non-destructively tracing dampness in building materials of all kinds as well as for
detecting damp distribution in walls, ceilings and oors. It is particularly suitable for pretesting the readiness of building
materials for covering prior to CM measurement.

Adjustment
The instrument is calibrated fully electronically and readjustment is not necessary.
Precautions
This is a risk of injury if the metal ball comes into a contact with live parts.
•
Use the instrument only for measuring the dampness in hardened building materials by bringing the ball into a
•
contact with the surface.
Do not take measurements on metallic linings.
•
Take measurements at distance 8-10 cm from the edge/recess.
•
Instrument check
Hold the instrument as near to the back as possible. Press the MEAS button and hold the instrument with the ball in
the air. The displayed value must be between -5 and +5.
Operation
Hold the instrument as near to the back as possible. Press the MEAS button and use the ball to scan the surface under
investigation. The ball must be in rm contact with the material. To obtain the best results, the instrument should be
held at angle of 90° to the surface to be measured.
If the icon appears on the LCD display, it indicates that the battery should be replaced. Open the battery case
and replace the battery with the new one.

Evaluation of results
The measuring results are for orientation and pre-evaluation only; it is not a qualied dampness measurement or
relevant to specialist regulations.
The raw density of the material being measured has a noticeable inuence. Basically, the value displayed with dry and
damp building materials increases correspondingly with increasing raw density.
If the surface to be measured is dirty this will have an inuence on
the measuring result. Please remove any dirt from the surface.
Do not take measurements on metallic linings! In corners or recessed areas a distance of ca.8-10 cm form the edge/
recess must be maintained.
If the measured surface is of rough structure measured values will be higher.
Measured values can be taken from 20 mm up to 40 mm depth.
Underlying layers cannot be measured.
If the material measured has a thickness of less than 20 mm other material layers can inuence the measured value.
