SPECIAL FUNCTIONS

6.1 SPECIAL FUNCTION KEY AND DIGITAL INPUT

The

key (special function key) in the frontal panel of the controller as well as the Digital Input

may be assigned different functions that will be chosen by the user during the setup: These functions
can be chosen independently, both for the

key and the Digital Input. The

key and Digital

Input functions are explained below.

6.1.1

kold – Freeze measured value

The hold function freezes the measured value showed in the display. Each time the

key or the

Digital Input is selected, there is a change from hold to normal mode.

Whenever the indicator is in the hold mode, the message “koLd” will be displayed so that the
operator will be aware that the value displayed is the frozen value and not the current reading.

6.1.2

Pkold – Maximum value

The indicator will automatically work in the Peak Hold mode whenever the

key or the Digital

Input are programmed as “PkoLd”.

While in this operation mode the indicator always shows the maximum value measured, since the last
time the

key or the Digital Input were pressed.

Each activation of the

key or digital input triggers a new Peak Hold cycle and the display resets

with a new peak value.

6.1.3

xi – Displays Maximum

Displays the maximum (High) value the indicator measured since the last reset.

6.1.4

Lo – Displays Minimum

Displays the minimum (Low) value the indicator measured since the last reset.

6.1.5

rESEt - Clears Maximum and Minimum

If this “rESEt” function is programmed, every touch of the

key or Digital Input activation clears

the memory and a new cycle of maximum and minimum values memorization will start.

6.1.6

zero – Zero Function

Available only for the

key. It resets the scale. This function is used to eliminate the influence of

interference or small deviations in the zero of a scale. Reset is only accomplished if the value shown
in the scale is within 2% of the end of scale. Zero is not lost if the scale is turned off.

6.1.7

tarE – Tare function

It is available only in the Digital Input configuration or through the

key. It changes indication to

zero (0000.0), regardless of the value applied to the input. It is used to eliminate indications of defined
values. In order to eliminate the tare, the user must press the

key.

6.2

AND

KEYS

The same Tare function available for the Digital Input can be quickly applied by using the

key,

which does not need to be set up. The

key is used to eliminate the tare applied.

The indicator accepts successive tares provided that the input signal (gross weight) does not exceed
the equipment end of scale.

6.3 POWER SUPPLY FOR LOAD CELLS (10 VDC)

N1500LC provides a 10 Vdc (or 5 Vdc) output to excite load cells. This power supply capacity is 50
mA.
