The ‘

On Power Up

’ (‘

on.Pu

’) menu configures functions to apply at 

start-up. It applies only to instrument restart after power loss. It does 

not apply to instrument restart due to change in configuration.

• parameter ‘

Delay

’ (‘

dLAy

’) assigns a waiting time in seconds. The 

instrument waits the configured time before starting normal func

-

tion. During this waiting time, the display shows all decimal points 

on in flash mode, all alarms are in ‘oFF’ state, there is no signal acqui

-

sition and there is no communications or control being performed. 

After  the  configured  time  is  over,  the  instrument  starts  in  normal 

function. Delay value between 0 and 200 seconds.

Application - the start-up process for an automation system implies 

that different parts of the system (engines, actuators, controllers, ...) 

have different start-up times. The ‘Delay’ function gives time to the 

instrument to wait until the slowest part of the system is fully func-

tional before executing actions on the system (signal reading, relay 

activation, ...)

• the ‘

Tare

’ (‘

tArE

’) functions allow to activate an automatic tare of 

the reading each time the instrument is restarted. See section 

1.10.9 

for more information on the ‘tare’ function.

1.10.8 Menu ‘On Power Up’

The ‘

Tare function

’ (‘

tArE

’) menu allows to operate the instrument 

for load-cell and weight applications. The tare function assigns the 

actual input signal value to a reading of ‘0’ Kilos, by adding an inter

-

nal offset. It does not modify the scaling parameters of the instru

-

ment.

The ‘Tare’ function can be applied pressing button ‘LE’ (

3

) at the 

front keypad 

(see section 1.10.10)

The offset value is eligible for visu

-

alization through the ‘

Fast access

’ menu 

(see section 1.10.6).

To work with load-cell applications it is important to first adjust the 

scaling of the instrument to the load-cell used.

Application - A load cell with 2 mV/V parameter, powered at 10 Vdc, 

with nominal weight of 500 Kilos, together with a signal converter 

that provides 4/20 mA signals for a 0/20 mV signal from the load-cell. 

The scaling to configure at the meter is 4/20 mA = 0/500.0 Kilos. Once 

the meter is scaled, the tare function can be used to ‘tare’ the reading 

to 0 Kilos.

• at the ‘

in memory.
