This instrument can measure the moisture content of biomass

fuel. Using a fixed sample volume allows the weight, temperature,

and capacitance (dielectric) of the sample to be measured.

After processing this information with the use of the embedded

microprocessor, the “Moisture Value” is displayed. Refer to the

“Product List” attached for measurable biomass fuel versions.

Because the calibration curves of products on the “Product List”

have been already stored, the measurement of a sample on the list

can be instantly performed by simply pressing the product number.

1. Features

[Note]

The entered product versions may be dierent even among the same

HI-700 models. The display may be dierent between examples in the

Operating Manual and the real ones on the actual tester, but the usage

is the same.

5. Preparation and Conguration

•

This instrument is equipped with an integrated weighing scale. For optimal results, this instrument should be placed on

a horizontal surface and used in locations where the wind is not strong and the instrument isn’t subject to vibration.

• Do not hit the instrument during operation and do not leave the instrument upside down.

• Although this instrument performs automatic temperature correction, for optimal measurement, leave this

instrument at ambient temperature for 2 hours or more before use.

• The temperature sensor embedded in the main unit measures the ambient temperature around the measuring

unit and automatically performs temperature correction. If the displayed measured value blinks (warning

indication), see “8. Error Display” on page 16.

5-1. Battery Installation

Theunit is powered by four 1.5 V batteries (A A ,

manganese). Remove the bottom batter y cover,

place the batteries into the compartment, ensuring

to correctly orient the positive (+) and negative (–)

terminals. Then replace the battery cover.

5-2. Product number viewing

(1) Press the key.

(A buzzer sounds for 2 seconds, and all contents are

displayed, the four-digit number in the upper left while

displaying the all contents is the version number.)

(2) The number of the product that was measured during

the last test is displayed. In the case of the drawing

(right) the product number is “01 PKSD”.

5-3.Product number selection

Select a product number to be measured from the

"Product List".

(1) Ever y time the key is pressed, the product

number is displayed in the following order:

"01→02→03→04→· · ·".

(2) For example, to change to “04 WP” when “01 PKSD”

is displayed.

(3) Press the key 3 times to adjust the product

number to "03".

(4) Now, “04 WP” is selected.

[Note] The product number is memorized while

the instrument is off, and therefore, the

last selected number is displayed when the

instrument is turned on the next time.

6-1. Manual hopper

6. Sample Extraction and Measurement

Use of Manual hopper

6-2. How to extract a sample

(1) Mount the funnel on the manual hopper, and load

a sample into the funnel to one-third of the funnel

depth.

(2) Remove the funnel to eliminate surplus sample and to

level o the sample.

[Note] Never extract a sample directly with the manual

hopper.
