6.1 System parameter setting
In the basic display state, press and hold key for 2 seconds. Enter the field parameters, set
the LOC = 800. Then press the button to confirm and enter the system parameter setting
state. , , key can directly modify the parameter values. Press the key to
reducing the data, press the to increase the data. Waiting to modify the value of the decimal
point will flash (like a cursor). Press key and hold, you can quickly increase / decrease in value,
and the speed will be automatically accelerated. Also press the key to move to modify the
data location (cursor), the operation is more efficient. key can be stored to modify
parameter values and display the next parameter, press and hold key 2 seconds, and can
return to the previous parameter; can immediately exit the parameter setting state.

6.2 Set value setting
In the basic display state, press , , key can directly modify the given value.
6.3 “At”PID parameter auto-tuning
Press and hold for 2 seconds, the At parameter appears,"At" parameter "OFF" is set to "ON"
and then press the key to confirm instrument can start the implementation of the autotuning
Given function, the instrument in the basic display state display will flash the word "At",
the instrument after 2 oscillation cycle ON-OFF control can automatically calculate the PID
parameters. If you want to advance to give up auto-tuning , "At" parameter “ON” is set to “OFF”
and then press key to confirm.
Given tuning parameter values obtained are not identical, to perform auto-tuning function,
should be first given value set in the most commonly used value or middle value, if the system
is good insulation properties of the furnace, the given value should be set in the system uses
the maximum, and then Execute the start of the operation of auto-tuning function. Reasons to
learn, auto-tuning after the initial use, the effect may not be the best, you need a period of time
(usually the same time auto-tuning control) before they can get the best results.

preferable to shorter, usually 0.5-3.0 Seconds. The
relay switch output is generally in 15-40 sec. When
the output relay switches, the CP will be limited to
3 seconds, and self-tuning At will automatically set
the CP as the appropriate value, taking into account
the control accuracy and mechanical switch life.

HYS is used for on-off control to avoid frequent on-
off action of relay. For a reverse acting (heating)
system, when PV > SV, output turns off; when
PV<SV-HYS, output turns on. For a direct acting
(cooling) system, when PV<SV, output turns off;
when PV>SV+HYS, output turns on.

Sc is used to shift input to compensate the error
caused by transducer, input signal, or auto cold
junction compensation of thermocouple.

cause measurement inaccurate.

InF
PV
input filter
The value of InF will determine the ability of filtering
noise. When a large value is set, the measurement
input is stabilized but the response speed is slow.
Generally, it can beset to 1 to 3. If great interference
exists, then you can increase parameter “InF”
gradually to make momentary fluctuation of
measured value less than 2 to 5. When the
instrument is being metrological verified, “InF” s can
be set to 0 or 1 to shorten the response time.

10 Note
(1) Can not normally display measured values in the display window alternating show:
"orAL" character, indicating that the input of the measurement signal abnormalities or Out of
range; check Int parameter settings, and then the input sensor signals are the same category,
if it is determined the same, check the input sensing Signal not pick the wrong line, if it is
determined to not pick the wrong line, check whether the sensor problem, replace another
sensor to try.
(2) The instrument used by the local environmental temperature and humidity can not
exceed the scope of the provisions, the instrument around should allow sufficient space for
heat dissipation, instrument internal temperature rise due to thermal radiation will lead to a
result of the measurement accuracy and service life of the affected. In this Case, to be taken
to a forced cooling fan or other measures to reduce the ambient temperature.
(3) the extension or connection then the thermocouple leads should be used with the
thermocouple type to match the compensation conductor; extend or connect the
thermoelectric Resistance of the lead, you should use the minimal resistance of the wire and
cable away from power lines and load connection, in order to avoid signal interference.

12 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
