surface. Use a hammer to insure the sleeve is fully inserted into the hole and
sealed to the concrete.
⇒ Insert the protective yellow cap into the sleeve and let the hole acclimate for 72h.
Optional plugs (p/n CS-Plug) are available in three sizes that will isolate a 0.062
space at the hole bottom during acclimation time.
⇒ Remove the cap and immediately insert the RH probe sensor to full hole depth.
Wait minimum 1h. Connect one end of the RH/T-C1 cable to the top of meter
and the other end to the exposed end of the probe sensor. Take reading using
the RH/TEMP mode of TotalCheck as described on pages 10 and 15.
⇒ Alternately, insert the RH probe sensor into the sleeve immediately after setting
the sleeve. Readings can then be taken as soon as the hole has acclimated.
Note that continued and long term exposure to high humidity may damage the
sensor irreversibly.

Refer to the White Paper, “Relative Humidity Sensor Behavior and Care” on our website
for additional information regarding the sensor itself.
TESTING INSULATION:
⇒ Set the meter scale for the “REL 0-100” as described in the Create/Edit a Job
section on page 12.
⇒ To take a reading, attach a 21-E electrode with 4” insulated contact pins to the
meter. Push the contact pins through the drywall into the insulation behind it.
⇒ Press the SELECT button and read the moisture content on the meter scale. The
meter displays the “relative” moisture level for two seconds.
⇒ To add a reading to the previously stored readings, release the SELECT button if
you are in triggered mode. If you are in continuous mode, the meter will not store a
new reading until the SELECT button is pressed and released again during the
reading cycle.
TESTING DRYWALL
⇒ Set the meter scale for Sheetrock® as described in the Create/Edit a Job section on
page 12.
⇒ To take a reading, push the contact pins into the Sheetrock® to their full penetration,
if possible.
⇒ Press the SELECT button and read the moisture content on the meter scale. The
meter displays the %MC for two seconds.
