• Comes with 2 types of sensors
Includes a pressure sensor for measuring each jute separately and a 2 needle probe that allows jute
to be measured in stacked formation.
• Handheld device with large built-in display
The portable handheld device features a large 76mm x 52mm display that's very easy to read.
• Bias adjustment
The moisture value can be corrected corresponding to each calibration in the range from
–9.9% to +9.9%.
• Auto power off
When inactive, the unit will automatically turn itself off after approximately 5 minutes to avoid
draining the battery.
• Alarm setting
Set any moisture value, and an alarm will sound if the measured moisture value is higher than the
set moisture value.

6-1. Before Measurement
1.The unit is powered by six 1.5 V batteries (AA, alkaline). Remove
the rear battery cover, place the batteries into the compartment
taking care to correctly orient the positive ( ) and negative ( )
terminals. Then attach the battery cover.
• is displayed when the batteries are depleted. Replace all six with
new batteries.
2.When using the 2 needle probe, attach the measurement
needles to the grip. Insert the measurement needles into the
socketsattheendofthegripandtightenthexingscrewswith
the hexangular Allen wrench (included). When inserting, orient
the concave part of the measurement needles so that they come
in contact with the head of the screw as shown in the diagram.

3.Plug the probe connector into the socket on the main unit, and
fasten and secure the lock ring.
4.Prepare the jute sample to be measured. Allow the sample to
equilibrate to the same temperature as the main unit.
• Errors may occur when there is a large difference in the temperature
of the jute and the temperature of the unit. To make more accurate
measurements, allow the temperature of the jute to equilibrate with the
temperature of the unit.
