0-50 mVZ range are divided into 16 egual parts. Every “Poxx” SET value is defined
50 / 16 = 3.125 mVZ range.
Operating Scale Maximum Value
(Scale Low Point, Scale High Point)Unit
Used for Proportional band calculation and display blink.
Display offset for process value (Scale -10%, Scale
+10%)Unit
This parameter value is added to the process value.
Filter Time (0.0, 900.0)Second
Defines filter time for display value.
Cold Junction Compensation
This parameter is active if process input is selected TC input.
Cold junction compensation is active.
Cold junction compensation is not active.
Scale: The difference, between high point and low point of the process
input type. Example: If tCSL = 2 (low point is -200, high point is 900),
then scale is 1100. If input type is Voltage/Current, then the scale is
difference between tPoH and tPoLparameters.

If there is danger of serious accident resulting from a failure or defect in
this unit, power off the system and separate the electrical connection
of the device from the system.
The unit is normally supplied without a power switch or a fuse. Use
power switch and fuse as required.
Be sure to use the rated power supply voltage to protect the unit
against damage and to prevent failure.
Keep the power off until all of the wiring is completed so that electric
shock and trouble with the unit can be prevented.
Never attempt to disassemble, modify or repair this unit. Tampering
with the unit may results in malfunction, electric shock or fire.
Do not use the unit in combustible or explosive gaseous atmospheres.
During the equipment is putted in hole on the metal panel while
mechanical installation some metal burrs can cause injury on hands,
you must be careful.
Montage of the product on a system must be done with it’s mounting
clamp. Do not do the montage of the device with inappropriate
mounting clamp. Be sure that device will not fall while doing the
montage.
It is your responsibility if this equipment is used in a manner not
specified in this instruction manual.
Before beginning installation of this product, please
read the instruction manual and warnings below
carefully.
In package ,
- One piece unit
- Two pieces mounting clamp
- One piece instruction manual
A visual inspection of this product for possible damage occured during

this product.
Kessler-Ellis Products warrants that the equipment delivered is free
from defects in material and workmanship. This warranty is
provided for a period of two years. The warranty period starts from
the delivery date. This warranty is in force if duty and
responsibilities which are determined in warranty document and
instruction manual performs by the customer completely.
Repairs should only be performed by trained and specialized
personnel. Cut power to the device before accessing internal parts.
Do not clean the case with hydrocarbon-based solvents (Petrol,
Trichlorethylene etc.). Use of these solvents can reduce the
