5. Moisture analyzer calibration
The moisture analyzer uses the relative weight to measure the result, so a small
deviation from the absolute weight has less influence on the accuracy of the
measurement. The moisture analyzer is stable in weighing performance and has
a small temperature influence, which can maintain the calibration result for a
long time, so weight calibration is not necessary. Before calibration, confirm
that the Moisture analyzer is empty in the weighing mode, and there is no any
other things on the weighing pan.
Preparation
1. Place the machine on a solid, horizontally position, table or platform and
then adjust the level.
2. Turn on and warm up the machine at least 30 minutes.
The calibration/adjustment only can be make in the following situation
The machine will show the calibration weight only if reach below requests
※ The machine must be warm up in advance.
※ The machine is not overload, already tare the weight, inner signal stable

After 5 seconds , display will show 100.000g
Remove the weight and the calibration is over.
6. Step of measurement
Note: Please set the heating method and temperature refer to the menu 4.
6.1 Press Tare key, make sure that machine display 0.000g and then put the sample evenly
on the weighing tray.
6.2 Close the heating compartment lid, press [START] key to start the measurement when
machine display stable.
On the left of display, flash means machine are under heating condition.
6.3 After finishing, the display will show the sample’s moisture value.
Press [Set] can switch to check the other testing result. Press [TARE] key can exit and return
to standby mode and wait for a new testing.
Note: 1. During measuring, user can press [STOP] to call off the testing.
2. DO NOT open the lid (cover of heating compartment) during testing.
After finish the test , user can press SET key to check each data of above.

7. Optimize the testing
During the heat drying process, the moisture is determined by the weight loss of the sample.
The speed and quality during the measurement can be referred to the following parameters.
The following parameters can also be determined by several trial experiments to determine
the best settings. The best test results depend on the following settings:
Heating temperature
Heating time
Sample weight
Sample preparation
Sample species
7.1 Heating temperature
The heating temperature control the measure time long or short. Example, heating
temperature low will longer the sample dried time. Set an appropriate heating temperature
and make sure that the chemical structure of the sample can neither be decomposed nor
changed. It is generally set to 105 ℃, except if the sample and user have special
requirements.
Some samples have different moisture content at different heating
temperatures. In this case, try to adjust the heating temperature to compensate for the
measurement deviation.
7.2 Heating time
The moisture analyzer provide three simple way
Auto mode (recommend mode) --- When machine detect a change in weighing results, it
automatically stops when the sample weight loss is less than the set value for a specified
period of time (usually one minute).
Hand mode --- Moisture analyzer in accordance with the user through menu 4.6
customize mode - stop conditions set weightless values and detection time values, to meet
the set condition values when the machine automatically stop.
Timed mode --- The heating time is set manually, i.e. the heating is automatically
stopped after the set time, ending the measurement.
Setting range: 0 to 99 minutes.

7.3 Sample’s weight
★The weight of the sample affects the measurement time and the repeatability of the results,
with a maximum sample weight of 50g.
★The more samples on tray , the more water is evaporated and the testing process is
prolonged.
★Sample weight is recommended at around 5-10g. Samples of 2g get faster results, but lack
of accuracy. Samples of 20g usually get consistent results, but take longer to test.
★Another way to measure sample weight is to use the relationship between sample weight
and moisture resolution, as below list:
Sample weight Repeatability Sample weight Repeatability
0.5g ±1.0% 5g ±0.1%
1g ±0.5% 10g ±0.05%
2g ±0.2% 20g ±0.02%
For example, if the moisture resolution result need to reach ±0.3%, in the table, mention that
the sample weight should be at least 2g. (The following test data is for informational
purposes only)
7.4 Sample preparation
Samples need to be representative of the test in order to obtain accurate and repeatable
measurements.
When preparing samples, ensure that the samples are placed evenly on the sample tray to
avoid build-up and excessive quantities
7.5
★Pasty, fat-containing soluble samples
Use fiberglass membranes to increase the surface area of the sample, for example, butter.
The water in these substances is distributed more evenly through suction cups. Increasing
the surface area of the sample causes water to evaporate faster and more completely
★Liquid samples
Liquids form droplets on the sample tray, which prevents quick drying. In this case, the glass
fiber membrane can be used to distribute the liquid sample evenly in a large surface area,
which can shorten the drying time.
15

★Easily crusted, temperature-sensitive samples
Samples that form shells on the surface can completely hinder the measurement of moisture.
At this time, use fiberglass membrane covering the sample, and with a milder and more
suitable heat, can improve the repeatability of the sample.
★Sugary samples
Samples containing a lot of sugar are easily burn. Make sure that the sample is evenly
distributed into a thin layer and set a moderate temperature. Glass fiber suction cups can also
be covered in samples to improve their repeatability.
