Safety Precautions

Desktop power supply 6971991:

An adaptor rated to Class 2 can be plugged into any

wall outlet with no additional safety precautions

required.

A ground or earth terminal is connected to the

balance housing. The balance housing can be

additionally grounded, if required for certain

functions.

The data port is also galvanically linked to the

balance housing (mass).

Connecting Electronic Peripheral Devices

t Make sure that the balance is unplugged from the

power supply before connecting | disconnecting

a peripheral device (printer or PC) to or from the

interface port.

Warm-up Time

In order to provide accurate results, the instrument must warm up for 30 minutes. Only after this time will the required operating temperature have been reached.

Anti-theft Locking Device

To fasten an anti-theft locking device, use the lug

located on the back of the balance.

t Secure the balance at the place of location,

e.g., with a chain or a lock.

Levelling the Balance

Purpose: – To compensate for unevenness at the place of

installation

Always level the balance again any time after it has

been moved to a different location. Only the 2 front

feet are used for leveling.

t Screw in both rear support feet (only on models with

a rectangular weighing pan).

t Turn the front levelingfeet as shown in the

illustration until the air bubble is centered within

the circle of the level indicator.

> Normally, several leveling steps are required.

t On models with a rectangular weighing pan:

Screw out both back leveling feet until they touch

the setup surface.

Below-Cell Weighing

A port for a below-cell weighing hook is located on

the bottom of the balance.

y Not permitted for applications in legal metrology.

t Lift cover plate out of the bottom of the balance.

Attention: Place the balance on its side, do not turn

over completely!

t Secure hook 1: Use a wire, for example, to suspend

the sample on the hook.

y Install a draft shield if necessary.

Calibration and Adjustment

Purpose

Calibration is the determination of any

difference between the measured value displayed and the true weight (mass) of a sample. Adjustment is the correction of this difference, or its reduction to an allowable level within maximum permissible error limits.

Features

Calibration | adjustment can be

performed only when – there is no load on the balance – the balance is tared – the internal signal is stable – the weight displayed for the sample on

the balance must not differ from the

nominal weight by more than 2%.

If these conditions are not met, an error

message is displayed “Err 02".

Following calibration | adjustment, the application program is cleared.

Internal Calibration | Adjustment

Note:

Only for models with the label Entris...i-1S !

In the operating menu, select

Cal.Just. - cal.int. before beginning.

The built-in motorized calibration

weight located in the housing is applied and removed automatically for internal calibration.

t Select calibration | adjustment:

Press Q
