1Your balance smooths the way

1.1 A new era in microweighing

The MT/UMT models open up new dimensions in microweighing, yet are simple to operate.

The separation of weighing cell and evaluation unit ensures maximum precision - disturbing thermal influences are practically eliminated. Automatic door functions facilitate operate and prevent vibrations. And there is no need whatsoever to concern yourself with the adjustment - your balance performs the adjustment fully automatically. Built-in data interfaces ensure that your balance can communicate with a computer and peripheral devices.

Your balance is distinguished primarily, however, by its user friendliness: You attach the weighing cell to the evaluation unit, connect the balance to the power supply and after 60 minutes warm-up time (with an acclimatized balance) you can immediately start weighing. You thus obtain your first weighing result in an extremely short time.

The MT/UMT microbalances offer you the operating convenience and the possibilities that to date were possible only with analytical balances. There is, however, no need for you to grapple at the moment with functions you will not need until later.

In this first section you will find out how simply you can start up your new balance and perform normal weighings.

1.2 Preparing your balance

If you fold out the front fold-out, you have in front of you an immediate overview of all general illustrations at a glance.

You need undertake the following operations only on first-time installation and each time you change the balance location.

- No direct sunlight

- No extreme temperature fluctuations

- No extreme fluctuations in the atmospheric humidity

- No excessive drafts (e.g. due to powerful air conditioning units)

Unpack your balance

Your balance is dispatched to you in a rugged packaging that you should store in a safe place for possible future transport of the balance.

As soon as you have decided on a suitable location, remove all components of your new balance from the packaging.

Set up the balance

You can set up the weighing cell to the left or right of the evaluation unit. The flexible arrangement of the balance allows optimum adaptation to your method of working and to the available space.

Connect the evaluation unit and the weighing cell

- Plug the supplied connection cable into connection socket 7 of the evaluation unit (marked with “For connection to weighing cell only”) and plug the other end into connection socket 19 of the weighing cell (marked with “For connection to evaluation unit only”). It is immaterial which end of the cable you connect to the evaluation unit or the weighing cell.

- The screws of the cable connectors have holes and can be sealed to prevent inadvertent separation of weighing cell and evaluation unit.

Mount the weighing pan and the draft shield

- The MT balances are supplied with mounted weighing pan. You thus only need to mount the glass cover on draft shield 12 of the weighing cell.

- The UMT balances have a smaller weighing pan than the MT balances (to avoid cornerload errors). The weighing pan is already mounted, on delivery. You thus need only mount the glass cover on the draft shield 12 of the weighing cell.

Level your balance

- Turn the two screw feet 18 at the rear of the weighing cell housing until the air bubble is in the middle of level 16.

Connect your balance to the power supply

- Connect the AC adapter supplied to connection socket 9 at the rear of the evaluation unit and then to the power supply.

Operating instructions METTLER TOLEDO MT/UMT balances

- The AC adapter can either be placed on the bench or, to save space, mounted on the wall. The AC adapter holder and the installation set with dowels and screws are used for this. Appropriate details are given in Section 6.1.

After connection, your balance is on standby. If your balance is already acclimatized (depending on the temperature difference between the old and new location, this takes 6 to 12 hours), it provides you with the first reliable results after 60 minutes warmup time. After approximately 2 hours you can count on very accurate weighing results.

1.3 Weighing made simple

- By pressing the «On/Off» key you switch your balance from standby to the weighing mode. The balance now automatically performs a brief self-test and all display segments light up briefly.

At the end of the self-test, the balance determines the zero point. This very precise measurement takes several seconds, depending on the stability and acclimatization of the balance.

STANDBY

After being switched off, the balance is on standby. When it is switched on again, it needs no warm-up time and is in immediate operational readiness.

Some additional tips:

- If you have made a mistake during weighing, there is no need to worry: Simply switch off your balance briefly and then switch it on again. You will later learn of other possibilities to bring your MT/UMT to weighing readiness again.

- You can also effect the zeroing (taring) of the balance using the foot or hand switch (available as an accessory) attached to the balance via connection 3. Operation with the foot switch leaves both your hands free for loading the balance.

operating convenience

2.1 An ergonomic glass draft

shield

The small, circular glass draft shield reduces the contact surface for disturbing thermal influences and thanks to the narrow framework allows an unrestricted view of the weighing sample.

The weighing chamber can be opened at the left or right. The balance is thus equally convenient to load for left- and right-handers.

You can operate the draft shield manu- ally in the traditional manner using door handle 14.

- In one-handed operation, you use one hand to press the or key and then load the balance using the same hand.

- In two-handed operation, you press the or key with one hand and load the balance using the other hand.

In certain applications, such as zeroing (taring) of the balance, the draft shield opens and closes fully automatically as you already know from your first weighing. Manual or semiautomatic operation is also possible when the fully automatic door function is operative.

The fully automatic door function primarily facilitates work with the single or twin foot switch. Section 3.4 shows you how to switch off the fully automatic door function.

The draft shield of your balance has a “Learn function”. If the fully automatic door function is in operation, the draft shield opens automatically when the balance is zeroed and when the weighing result is printed out on the side you desire. For this purpose, the balance notes which of the keys or you last pressed to open or close the draft shield.

2.2 The DeltaTrac® - an informative display

The DeltaTrac® 22 is a supplement to the digital display 23. It provides you with a pictorial representation of the

weighing range in use and that still remaining. The dynamics of a weigh-

ing process can be followed on the DeltaTrac® extremely well. Simply observe the DeltaTrac® during a weighing and you will immediately understand its function.

The DeltaTrac® gives you a new feel for weighing, even with special applications, for example in repeated weighing in to a specified target value and in percent weighings. You will find further details in Section 5.2.

2.3 How you can weigh in the coarse and fine range

Your balance is equipped with a switch key which you can use to switch from the ten times more accurate fine range to the coarse range.

This switching allows you to work in the range best suited to your needs.

If, for example, instead of a high resolution you need a stable weighing result as rapidly as possible, you switch from the fine range to the course range using the switch key. This makes your balance very fast and the weighing results are extremely stable.

You have the following selectable ranges available:

Balance Fine Coarse Key

This setting is suitable for very

calm and stable surroundings.

The balance operates very rapidly, but is relatively sensitive to external disturbances. This setting is recommended if your balance is located on a stone table.

3.4 How to switch off the fully automatic door function

You are already familiar with the convenient automatic door function of your balance from your first weighing. When the automatic door operation is switched on, the draft shield closes automatically after the «Re-Zero» key (zeroing/ taring) or the «Print» key (printout of the weighing result, see Section 5.6) has been pressed. As soon as the weight display is stable, the draft shield is reopened for the next weighing operation (e.g. weighing in, loading the balance). The draft shield is thus always in the correct position for the next weighing process. Routine work is particularly facilitated by this automatic operation. It is also useful in the percent weighing (Section 5.2) and piece counting (Section 5.3) applications.
