DIGITAL PID CONTROLLER

Setting decimal point position (DP-P), and free scale high and low limits (SL-H, SL-L)
(4) Digital input filter (FILT)
(5) Input value bias (BIAS)
This applies only when using voltage inputs (DC V, mV) or currents between
4 to 20mA (1~5V). The user may set ranges, units and decimal point position
as desired. This can be used not only for temperatures but also for a number
of other measurements, including humidity, pressure, and weight.
This function is useful when suboptimal environments cause noises or severe
fluctuations, enabling a digital software filter. The filter's sensitivity may be set
from off to 1~120 seconds. Please be careful when using this function, as it
may affect the control-related algorithms.
This function allows the input values to be compensated. This function is
useful, for example, when sensors can not be placed at desired locations, or
when several different thermometers are used in conjunction. The values may
be compensated to extent desired by the user.

(6) Correcting upper limit of input value(GAIN)
(1) Input type selection
(2) Input unit selection (℃ / ℉)
This is the first thing that needs to be checked and set before using the T50,
as the settings here will cause other parameters to be reset to their typically
optimal values for that specific type.
This selects the unit of temperature measurement to be displayed when using
temperature sensors. The Celsius degree is set as the default, but it may be
changed to the Fahrenheit degree. On products sold in Korea, the units are
fixed to the Celsius degree in compliance with the regulations.
It is used only in the voltage input (current 4 to 20 mA) mode, and can
accurately correct the indication deviation due to the output tolerance of
the sensor modulus and the tolerance of the conversion resistance
(250Ω).
It is used with BIAS, BIAS adjusts the offset and GAIN adjusts the slope.
For example, when using the current (4 ~ 20mA) input, the tolerance is
corrected by BIAS when the minimum value (4mA) is input and the tolerance
is corrected by GAIN when the maximum value (20mA) is input.
※ For reference, correcting
BIAS before correcting
GAIN must be done first.
The T50 series also offers
a powerful compensation
function that allows
accurate measurement
even without using a
high-precision (± 0.1%)
class with a 4 to 20 mA
conversion resistance
(250Ω).
