MM70- English only manual-2P-060408:Layout 1
INTRODUCTION:
The MM70 Precision LED Moisture Meter has an ergonomically-
designed shape and uses a new type of circuit design. It is highly
accurate, responds quickly, and has passed CE and RoHS electric
security and green regulatory.
APPLICATION:
The MM70 can be used to measure the moisture (%) of wood,
architectural material and the moisture equivalent (%WME) of
most material. It is very practical for quality control and
management/inspection after-processing or before-processing, and
business trade.
PREPARATION:
1. Please check all equipment before using the instrument:
Main instrument
Replacement needle screw
Protection cap
Soft portable leather case
Needle probe
"9V" battery (option)
Replacement needle
Instruction manual
(including wood calibration table)
2. Please push down the round marks on battery cover and slide
out the battery cover at the same time. Then, place a "9V"
battery according to "+/-" and reinstall the battery cover.
USING THE MM70:
1. Remove the protection cap to expose the needles.
2. Switch the instrument power on by pressing
the green LED (ON) will light up and "beep".
3. Before the needles make contact with anything, the other LED's
will not be bright. If they are bright, please check or calibrate
the instrument.
LOW POWER WARNING: Complete the steps above to turn on.
If the top red LED (Low Batt.) flashes and makes a "beep" twice, it
represents low power. Please exchange with a new battery before
using the instrument.
4. Push the two needles into the object to measure the moisture.
When the instrument is stable, it will get an accurate reading.
It will make a short "beep" warning twice, then the LED display
will show the reading of the moisture value.

CALIBRATION AND INSPECTION:
This instrument has been calibrated completely before ex-work, and it
can be operated steadily for a long time with normal use without
needing any adjustments. For special conditions, if the instrument
needs to be adjusted, it is recommended to use a small "flat-head"
screw driver to do fine adjustments on the right side "CAL"
key,
potentiometer, or contact our technical department.
SIGNAL OUTPUT:
The MM70 has an analog signal output function, and can be used to
connect the recorder/logger or other equipment. When the MM70 is
used to constantly measure, it can be connected with the left output
socket under the instrument.

right side socket to assist in operating.
The reading value of the same object measured by either the
extension probes, or the needles is equal.

This instrument has an auto-power off function. The instrument
will turn off automatically to save power after 40 seconds of
non-operation.

but also a multi-color indicator to show measurement of the
moisture percentage of material.
