3 Special instructions for XP-K comparators

To fully utilize the high resolution of the balance, some specific rules must be observed. These will enable you to obtain the best pos-

sible results.

3.1 Load the comparator

Because of the high resolution of the balance, even minute differences of temperature or humidity can affect the result. Make sure that

the weighing pan is clean and that the weighing sample is acclimatized.

– Always use gloves or working aids that do not damage the weights when loading and unloading the bal-

ance.

– When loading the balance you may use aids (e.g. crane) with a maximum speed of 5 mm/sec. A higher speed

can have negative influences on the weighing result.

3.2 Settings for the XP-K comparators

3.2.1 Factory setting differences compared to the standard types

AutoZero: Is switched off at initial operation and after a factory reset (resetting to the factory settings), but can be switched

on again when required.

When changing over to the “WeighCom” application, “AutoZero” is automatically switched off. When changing

back to the “Weighing” application, the previous status of “AutoZero” is restored.

When comparing masses, “AutoZero” must not be switched on, because it can distort the measurement

values.

ProFACT: Is switched off at initial operation and after a factory reset (resetting to the factory settings). When comparing

masses, it is not advisable to switch “ProFACT” on.
