INTRODUCTION

About Your Meter

The C555 sensor pad measures 2.0-inch
(50mm) wide by 2.5-inch (63mm) long.

Where appropriate, or when specied, use

further testing as outlined in ASTM F2170.

Your Wagner Meters C555 hand-held
concrete moisture meter was designed to
make a fast assessment of concrete slab
drying patterns easy and inexpensive.
Large areas can be surveyed quickly and
easily. Wagner meters are nondestructive.
They do not require drilling or driving
pins into the concrete. Your model C555
has the built-in capability to capture and
record relative humidity and temperature
readings to determine ambient or service
conditions.

The C555 is designed to give an average
moisture indication of the area it is
scanning. However, using readings
from surface concrete moisture meters
should NEVER be the sole factor when
determining if a concrete slab is dry

enough to install a oor covering.

In the Standard Measurement mode, your
C555 measures moisture within the 1% to

6.9% moisture reading range.

The C555 has an easy-to-read digital
display scaled in 0.1 increments when in
Standard Measurement mode.

QUICK START

BASIC USE FOR CONCRETE

With your C555 turned
OFF, press and release
the ON/HOLD button.
The meter will turn on and

briey display the model
number, followed by the rmware revision
number. If this is the rst time you are

using your new C555, the meter display
should revert to Standard Measurement
mode for concrete immediately after the
revision number is displayed, with the
display showing C 0.0 when the meter is
held in the air.

Press the MODE button until the display
shows CON, then press the ON/HOLD
button to enter the Concrete Reading
mode. A large C will be displayed while in
Concrete Reading mode.

The next press of the MODE button will
display REL. Press ON/HOLD to select.
This mode will show the relative reading.

The third press of the MODE button shows
CAL and is used for the calibration of the
meter. This mode is used in conjunction
with the included On-Demand Calibrator.
You will place the meter in this mode to

perform your own eld calibration. See

instructions on page 20.

When you are nished taking measurements

and wish to turn the meter off, press the ON/
HOLD button for approximately 2 seconds.
Alternatively, the meter will automatically
shut off after approximately 60 seconds of
no activity.

Press the MODE button
four times and the Relative
Humidity mode will display
RH for 3.5 seconds, then

it will display the ambient
relative humidity (e.g., 34.5%). After 3.5
seconds, the mode will change to temperature
and DEG will display, then toggle to the
ambient temperature (e.g., 75.1F). The
temperature display can be changed to
Celsius (e.g., 24.0C) by pressing either the
UP or DOWN arrow key.

CORRECT USAGE

GUIDELINES FOR YOUR C555

MOISTURE METER

To make sure that you are getting the
most accurate readings from your C555
meter, Wagner Meters recommends that
you pay close attention to the following
guidelines:

1. To prevent high or inaccurate
readings, always ensure there are no
metal objects near or directly under
the moisture meter.

2. The sensor plate is a 2.0-inch
(50mm) wide by 2.5-inch (63.5mm)
long rectangle on the back of the

meter (opposite side of the display).
To take a valid measurement, the
sensor plate must be completely
covered with the material you are
measuring. If the sensor plate is not
completely covered, your moisture
reading will be inaccurate.

3. If there is visible moisture or water
on the surface of the concrete to be
tested, wipe off any excess and let
the surface dry out for a few minutes
before taking measurements.

4. Be sure to press down with slight but

rm pressure to ensure good sensor

plate contact with the surface of the
concrete.

DETAILED USAGE INSTRUCTIONS

ON/HOLD Button

When the meter is OFF,
pressing and releasing the
ON/HOLD button will

turn the meter ON, with the meter briey

displaying the model number, followed by

the rmware revision number. Immediately
after briey displaying the revision

number, the meter will be in the Standard
Measurement mode. At this point, the meter
is ready to take moisture measurements.
Be assured that any settings that you have
previously programmed/selected will be
active. In other words, turning off the meter
will not cause the meter to revert to factory
default settings, but will retain whatever
settings you programmed it with.

When in the Standard Measurement mode,
pressing and releasing the ON/HOLD button
will freeze whatever reading is showing on
the display. Additionally, the word HOLD
