INTRODUCTION
ZFM 100-4 Non-Invasive Inductive Moisture Meter main by the sensor , at the back of the tool, emits and picks up electro-magnetic signals through the material to be tested. The reading displayed is an average value of the moisture content from the entire surface area and
the maximum depth of penetration. Moisture which is closer to the surface has a greater effect on the average value than the moisture close
to the maximum depth of penetration. ZFM 100-4 has internal auto-calibration function, therefore no need for manually calibration.
If the target depth is smaller than Max. measuring range 20mm, the value shows on the LCD is not accurate. The Max measuring depth
for this unit is 3/4 inch (20mm).
Notes:
The measured values of drywall and masonry are relative. Moisture degree is displayed in conditional units. Relative measurements
allow to control the change of humidity in the materials during the time. E.g. the process of drying out of plaster before laying the following layer.

FUNCTIONS
1. LCD display readings
2. Lock readings
3. Auto calibration
4. Low battery indicator
5. Detect Moisture of 4 different materials (drywall, masonry, softwood, hardwood)
6. Alarm if reading is out of range
7. LED bar indicates moisture value
8. Auto power off in 2 minutes inactive
OPERATION INSTRUCTIONS
1. Press power switch to turn on the device, and the device will start measuring.
2. Press Left or Right key to select measuring mode.
3. To get a moisture value, place the device on flat surface of the target object.
4. If the moisture value is out of measuring range, the buzzer will alarm.
Alarm Range a: Dry wall and Masonry
Buzzer alarm when value >70,
b: Softwood and Hardwood
Buzzer alarm when value>17%.
5. Press HOLD to lock current value, press again to release the lock.
6. LED will indicate the moisture content simultaneously when the value is shown on screen.

Red: 70+
b: Softwood and Hardwood
Green: 5%~14% Yellow: 15%~17% Red: 17%+
7. The device will power off if no operation in two minutes.
8. Hold power switch for two seconds to turn off the device.
Operation notes
1. Operate the device with care, place the sensor panel against target surface closely.
2. Depth of target object should be at least 20mm. If not, stack a few same objects to reach the minimum depth.
3. Area of target surface should be larger than sensor panel (40 x 40mm).
