(1)Remove the funnel and sample cup from the unit.
(2)Load the batteries.
The unit is powered by four LR6 batteries.
Place the batteries in the compartment correctly.
(3)The PM-600 features an integrated balance. For best ac-
curacy, place the unit on a horizontal surface, in a loca-
tion that is not subject to wind or vibration.
Attempting measurement while holding the unit in your hand
or in a location where wind or vibration is present reduce pre-
cision or make accurate measurement impossible.
(4)Prepare the sample to be measured before measurement.
Allow it to equilibrate to the ambient temperature of the
PM-600.

6-1. Turn on the PM-600
(1)Press key.
(Buzzer sounds for 2 seconds.)
All indicators will be displayed (Figure1).
(2)After 4 seconds, the product number (01~99) and the product
name (4 characters), "T" and "%" indicators will be displayed
(Figure2).

6-2. Select the Product.
Example : Product No. 41 to
Product No. 43
(1)Press key.
Be sure that Product No. "41" is blinking (Figure 3).
(2)Press key.
"1" is blinking (Figure 4).
(3)Press key (Figure 5).
Note : The product number is retained in the non-volatile
memory when the PM-600 power is off.

6-3. Pour the sample into the sample cup.
(1)Place the funnel on top of the sample cup.
Pour the sample to be tested into the cup until it overflows
(Figure 6).
(2)It shoud take about 4~5 seconds.
(3)Remove the funnel and level the cup by pulling the funnel
accross the top edge(Figure 7).
Caution : Never use the sample cup to take a sample directly
as shown in Figure 8.
Always use the funnel.

6-4. Pour the sample into the measuring section.
(1)Press key.
The decimal point blinks (Figure 9).
The PM-600 is performing zero-adjustment of the built-in scale
while the decimal point is blinking.
Caution : Be sure not to touch the unit at this moment.
(2)Pour the sample into the unit when the "POUR" indicator be-
gins blinking (Figure 10).
Caution : Pour the sample into the center of the measuring
section at a speed at which the entire sample is
poured in about 5 ~ 6 seconds.
Pour the sample in to be even (Figure 11).
Note 1 : For tea sample which is not so smooth as grain,
pour the sample, a little shaking the sample cup
and aiming at the center point of the unit.

Note 2 : When "Corn Cane" or "Flattened Barley" or "Tapi-
oca Flour" is measured, the sample is sometimes
put on the top of testing chamber as per Figure A.
In that case, drop the sample on the top into the
testing chamber while a decimal point is blinking
(Figure 12).
Note 3 : When "Pine Pulp" or "Tapioca Chips" or "Tapioca
Pellets" is measured, the sample may be put be-
tween testing chamber as per Figure B. In that case,
the sample which can not be put into testing cham-
ber should be either removed or cut fine into small
pieces prior to measurement (Figure 13).

(3)After the "POUR" indicator goes out, the decimal point blinks
10 seconds.
The moisture content and the number of measurement are
displayed (Figure 14).
The unit measures weight of the sample while the decimal
point is blinking after the "POUR" indicator goes out.
Caution : Do not pour more sample in during this period or
the measurement precision will be greatly down-
graded.
Do not put more sample into the measuring sec-
tion even if some spills out.
(4)Press key, weight/litre is displayed.(Figure 15).
(5) Dispose of the sample (Figure 16).
The moisture content or weight/litre is displayed during this
time. If you wish to continue with further measurement, re-
sume the procedure from step 6-3 "Pour the sample into the
sample cup".

Press key to display the average of the measured
values.
When the number of measurement is between 2 and 9, "AVE",
the number of measurements and the average moisture are
displayed (Figure 17).
Next press key, the number of measurements and the
average weight/litre are displayed (Figure 18).
Note : Once key is pressed the number of measure-
ments goes back to "1".

8. Performing Moisture Content Bias Adjustment
Moisture content bias adjustment can be made from -9.9~
+9.9% for each product.
Input a bias value if the moisture content has any discrepancy
against the official standard.
The bias value is not cleared, when the power is off.
Example : Product No. 41
BIAS value shoud be decreased by 0.4.
(1) Set the unit to the bias adjustment mode.
Confirm if the power is turned off.
Press key.
(2)Select the product.
Press key, key and key.

(3)Input the bias.
Press key.
The "BIAS" sign blinks. (Figure 22)
Press key, key and key (Figure 23,

(1)The battery indicator ( ) is displayed when the batteries are
exhausted (Figure 26).
Replace all four with new batteries.
(2)When moisture underflows the lowest limit of the measuring
range, LCD displays "A A A " (Figure 27).
(3)When moisture overflows the range, LCD displays "F F F " (Fig-
ure 28).
