1. Introduction
• The tester professionally measuring moisture in the material using probe and inductive sensors.
• The two modes can be switched at will, material moisture values can be displayed in real-time.
• Two materials can be measured in probe mode: wood and construction.
• In induction mode, 10 materials can be measured: Dry wall, Masonry, Hardwood, Softwood, Hard
gypsum floor (Wt%), Hard gypsum floor (CM%), Cement (Wt%), Cement (CM%), Concrete, Gypsum
plaster.
• Can be simple button operation and comfortable feel, so that users can use this instrument more
easily and quickly to measure.
Note: CM% is carb method and Wt% is water weight method.
2. Function

• When switched to the induction, the REL symbol appears.
• Probe shall be pressed into the material whenever possible.
• Induction measurement shall be as flat as far as possible.
5-3.Material Type Switch
• When switched to the probe type, 2 materials can be measured for wood and building, with
numbers corresponding to the numbers 0-1.
• When press the MODE Button briefly, the material number add 1,when numbered to 1, press the
MODE Button short and change the number to 0.
• When switching to the induction type, 10 materials can be measured, with the number
corresponding to the number 0-9.
• When short press of the MODE Button, the material number adds 1, when the number reaches 9,
press the MODE Button short, and the number changes to 0.
5-4.Automatic Shutdown Function

5-9.Functional Check
Probe-type functional inspection requires using the T contacts (T1, T2) and B contacts (B1, B2) on
the protective cover, as shown below:
1. Place the probe to the T1, T2 contact with the instrument reference is as follows:
Wood (10M): 18.3%±2%
Build (10M): 0.8±0.1%
2. Place the probe to the B1, B2 contact with the instrument reference is as follows:
Wood (680K): 25.9±2%
Build (680K): 1.2±0.1%
6.Product Maintenance
• If necessary, clean the equipment with wet cloth and unirritating detergent and wipe the machine
housing.
• Do not use corrosive or irritating cleaners.
• Clean the screen with a dry cloth.
