1 Safety instructions and warnings

WARNING:

Please read these installation and operating instructions carefully before starting

your work with the new scale. Any use of the device other than that specified in

this manual no longer guarantees the safety of the product. Keep the instruction

manual carefully.

Intended use

The iThermo moisture analyzer is used for the fast and precise analysis of liquid, pasty and

solid material moisture based on the thermogravimetric method.

Observe the following instructions for safe and trouble-free operation of the moisture

analyzer:

▪Use the moisture analyzer exclusively for the determination of sample

moisture. Any improper use of the appliance may endanger the safety of

persons and cause damage to the device or other objects.

▪Do not use the device in areas where there is a risk of explosion; also operate

the device only in compliance with the environmental conditions listed in this

instruction manual.

▪Do not use the device for chemically hazardous substances, toxic substances

that can cause biohazard, explosive flammables or substances that release

aggressive vapors when heated.

▪If electrical equipment is used in systems and in environmental conditions that

require greater safety measures, comply with the provisions of the directives

for the installation of this material in force in your country.

▪The device must only be used by qualified personnel who know the

properties/characteristics of the sample used.

▪Before operating the device for the first time, check whether the supply voltage

corresponds to the mains voltage.

▪To disconnect the device from the mains voltage, disconnect the power cord.

▪Lay the power cable in such a way as to avoid contact with very hot surfaces

of the device.

▪Use only extension cables that comply with the regulations and have a

protective conductor with a minimum operating temperature of at least 70°C.

Warning: protection against heat

▪Observe the following distance and the free space around the device to avoid

heat accumulation in the device and overheating of the device:

- 20 cm around the device

- 1 m above the device

▪Do not place flammable materials on, under or near the device as the heating

element overheats the surrounding area.

▪Remove the samples carefully, as the heating element and the sample-holder

plates may still be very hot. To avoid burns with parts of the high-temperature

oven, use thermally insulated gloves or pliers.

2 Installation

Gently remove the device from the packaging, check that the device has no visible damage

caused by transport and that there are all the accessories listed below.

2.1 Package Contents

1 Moisture determination tool.

2 VDE power cable

3 15-pole M/F cable for connection of the scale/heater

4 Underplate

5 Sample-holder plate extractor

6 Tray with antiventilation cylinder

7 #10 sample plates

8 CD with instruction manual

2.2 Positioning of the device

The device was manufactured in such a way that reliable weighing results are obtained under

normal operating conditions. The choice of the correct placement of the device is therefore

important to ensure optimal and precise operation.

To choose the place where to install the device, the following criteria must be met:

Do not install the scale in environments where there are

drafts, strong temperature changes.

Avoid exposure to extreme temperatures, as well as

temperature changes that occur, for example, if the device

is placed in radiators or in places exposed to sunlight.

Do not place the device near explosive and flammable

materials.

Place the device on a stable and level surface.

Avoid shaking during weighing.

The humidity of the environment of use of the scale must

be between 40% and 70%.

Do not expose the device to prolonged intense humidity.

Unwanted condensation on the device can occur when it is

cold and is placed in a room with a higher temperature. In

this case the device must be disconnected from the mains

and acclimated to the ambient temperature for about two

hours.

Level the device by adjusting the special feet 2 on the front

and one on the back of the device. The level bubble is

located at the rear of the heater.

Adjustable feet

2.3 Start-up

All the operations to be performed to prepare the device for the first start-up are described

below.

Open the oven lid and place:

1. Tray with antiventilation cylinder

2. Place the flat sample holder tray extractor

3. Place the star-shaped item on the weighing

cone.

The scale is connected to the heater via a 15-pole M/F

cable.

Insert the cable into the two connectors on the back

of the device as shown in the figure.

Insert the VDE cable supplied into the power

connector on the back of the device.

N.B. Check that the power supply shown on the

label of the device corresponds to the one in use

in the Country where you are installing the device.

Then connect the VDE cable to the socket located

near the device. Do not use cables/extensions that do

not comply with current regulations.

Wait 30 minutes after switching on and calibrate the

device after leveling it.

Perform device calibration whenever it is moved to

another location.

It is recommended not to drop objects of excessive

weight on the weighing plate of the scale to avoid

damaging it.

The assistance service must be performed by

specialized personnel and the spare parts used must

be original. To do this, contact the retailer where the

device was purchased.

3 Keyboard and display

The device is equipped with a backlit graphic display and a keyboard with six function keys.

The function of the keys varies according to the operations to be performed, and is

indicated in the part above the key in the lower area of the display.

➢% R Dry residue

➢% A Other (Ratio between initial

weight and final weight expressed in

➢g Weight

Key bar available at the end of the drying

cycle.

Exit key from the drying function

Key for activating/deactivating and

modifying GLP parameters.

Key for selecting the end-of-drying

parameter to be displayed, in rotation:

➢% M Moisture

➢% R Dry residue

➢% A Other (Ratio between initial

weight and final weight expressed in

➢g Weight

Key to print the result.

Parameter display key used for the

drying cycle.

4 Standby off function

After inserting the power cable into the mains socket, the device will turn on automatically and

after performing the system test it will be positioned on the standby screen.

Press the key corresponding to the power

symbol to start the device.

The device will be initialized and will

display the weighing screen.

To return to the standby status, press the

key again

Shutdown

To completely switch off the device,

remove the plug from the mains socket.
