This change is translated by the RWS and instantly and con- tinuously displayed on the large clear analog dial which gives comparative readings of 0 to 100. -
Page 7: Operation Modes
The RWS is designed to read through electrically non- conductive materials that are positioned between the electrodes and the substrate. For example: a conductive layer with metal lath or a wet surface could give false positive readings. -

1” (25mm) thickness of insulation. Hold the RWS by the grab handle and place it so that electrode is in full and firm contact with the surface over a known dry area. Adjust the sen- sitivity control knob until the needle is just above zero on the analog meter. -
Page 9: Interpretation Of Readings
Professional, with insulated deep wall probes may be useful in confirming an acceptably dry area. An alternative method is to use the RWS on a seek and find basis as follows: Place the RWS against the sur- face, adjust the sensitivity control knob so that the meter reads, say 50. -

Table 1. Comparison of RWS and Professional Pin Type Resistance Meter Readings It should be noted that calibration of the RWS in EIFS MODE was based on the averaged results of numerous on-site and laboratory tests. Therefore readings and results vary depending on construction detail and from site to site. -

In EIFS Or Similar Construction Once an area of excess moisture has been established, the RWS may be used to assist in tracing the moisture to the source of ingress as follows: Having found a wet area, turn down the SENSITIVITY knob until the needle points to approximately half scale (approx 50). -

Single Ply Roofing: Usually applied in welded • sheet form, direct to the insulation. Note: Using the RWS on black EPDM or Butyl rub- ber roofing may result in false readings due to the high dielectric constant of this material. -
Page 16: Correct Use Of Rws
Correct Use Of RWS. For correct use of your RWS : • Make sure that the RWS is held firmly by its built-in plastic grab handle and that your hand is not in contact with electrode or body sides of the instrument. -
