2.3 - Manual Operating Mode
The display shows the selected temperature value of the block and also the
current block temperature or thermo-element temperature value.
There are 4 ways in which the information are shown, covering the calibrator
input value (
IN
), the block temperature (
PROB
) and the temperature setpoint (
SET
). The
key
interchanges the display presentation way:
IN = 23.456 mV
PROB= 225.01 ºC
PROB= 225.01 ºC
SET = 225.00 ºC
23.456
IN = Voltage (mV)
225.01
SET = 225.00 ºC
The block temperature setpoint is selected directly by the keypad, even if the
message
SET
is not being displayed. The numeric keypad enables the
SET
selection in
any of the display presentation ways, to change the setpoint.
The setpoint value is increased by key
and decreased by key
. While the
keys are kept pressed, the setpoint continues to be increased or decreased.
The key
does not have function in the manual operating mode of the
T-350P/T-650P calibrators.
2.4 - Programmable Operating Mode
Pre-configured programs can be loaded from the calibrators memory, enabling
the programmable operating mode. The temperature programmed values of the block
are used directly, with no need to enter the setpoint.
The display shows
STEPn
beside the block temperature setpoint value in the
programmable mode. The number of the program is indicated by
n
. Using the keys
and
, the programmed values of temperature setpoint are changed. The numeric
keypad continues available for manual selection of the block temperature in the same
way of the manual operating mode.
The automatic scan over the programmed temperatures is implemented by
defining the stabilization time of the thermo-element in the block.
The key
enables the automatic scan over the points. When pressed, the
message
STEPn
gives place to
0s
and the calibrator waits for the stabilization time
configured from 1 to 9 minutes, by the keys
1
to
9
. The automatic scan is disabled by
pressing key
again.
