DEC_PRB: Selects the number of decimals of the block temperature and the
set point value. The default number is 2.
SP: Enables the calibrator Programmable Operating Mode, and allows the
configuration of programmed values. The selected program is indicated by the selection
arrow. Choose one of the 6 temperature programs or NO to disable this Programmable
Mode.
Select any of the 6 programs and confirm with the key ENTER. Following, it is
shown the menu of temperature set point configuration.
Change the configuration to steps (STEPS) of 10%, 20%, 25%, VARIABLE or press
C/CE to maintain the configuration already stored in memory. The temperature range of the
program must be configured through the values in SET POINT HIGH and SET POINT LOW
in case of 10%, 20% or 25% fixed steps of the range. The option VARIABLE allows the user
to define from 2 to 11 values of temperature set point, not necessarily in ascending order.
To verify the step values of a program, select the VARIABLE option and confirm the
values shown in the display with the key ENTER. The 10%, 20% and 25% options change
the number of steps automatically and recalculate the values according to SET POINT HIGH
and SET POINT LOW.
SC: Esta função realiza o escalonamento das leituras do termoelemento. O
escalonamento é muito útil na calibração de transmissores de temperatura, por
exemplo, pois facilita a visualização da temperatura atual e a leitura do transmissor na
mesma escala. O erro pode ser verificado diretamente em ºC ou ºF. Selecione a opção
SC e tecle ENTER. Caso nenhuma entrada esteja selecionada na opção IN, o
calibrador mostrará a mensagem SELECT INPUT FIRST. Retorne ao menu IN e
selecione o tipo de sinal de entrada.
SC: This function scales the input reading. The scaling is very useful in temperature
transmitter calibration, for instance, because it displays the current temperature and the
transmitter reading (mA) in the same unit. Thus, the error can be verified directly in ºC or ºF.
Select the option SC and press ENTER. If no input is selected in IN, the calibrator will show
the SELECT INPUT FIRST message. In this case, go to menu IN and select the input signal
type.
The function SC will show IN or NO. Confirm IN to configure the scaling or NO to
disable the SC function, with the key ENTER.
The scaling is performed via the INPUT HIGH and INPUT LOW parameters,
corresponding to the maximum and minimum values of the calibrator signal input, in the For
example, temperature transmitter with 0 to 100 ºC input and 4 to 20 mA output. The scaling
with one decimal would be:
