(6.1)"B" type duplex thermocouple
for controlling & over temperature
protection.
5.1
Power
Plug the black body power cord into a mains outlet of the proper voltage, frequency and current capability. Typically
this will be (230 VAC±10%, 50-60 Hz). Turn on the black body using "Mains" switch loacated at rear side. The black
body will turn on and begin to heat for previously programmed set point.
Note:
Ÿ
All other controller parameters are company set and locked. It is recommended not to change them.
Ÿ
When the source is operated at any temperature above ambient, the front face and plate become hot.
5.2
Setting the Temperature
Press “UP” or “DOWN” buttons to change the change the temperature set-point value. When the set-point
temperature is changed the controller will switch the CALsys 1700 ON or OFF to raise or lower the temperature. The
displayed temperature will gradually change until it reaches the setpoint temperature. The temperature bath
requires 15 to 20 minutes to reach the set-point depending on the span. Another 10 to 15 minutes is required to
stabilize the temperature bath within ± 2.0ºC of the set-point.
[!] Warning :
Do not connect or disconnect while power is on. Do not disconnect power when blackbody is
hot and fans are running.

Operating Instruction
Ÿ
After the completely installation.
Ÿ
Connect the 'CALsys 1700' to a suitable power supply. ON the Mains switch located at back side with power
entry.
Ÿ
Set the desire temperature value in PID by using UP & Down key.
Ÿ
Aim the reference (Master) standard infrared temperature sensor to the target area.
Ÿ
PV (Present value) display in controller will gradually rise until it reaches the set point temperature. The
controller takes some times to reach the set-point depending on the span. Furnace is stable when PV is equal to
SV (Set Value).
Ÿ
Master sensor take some times to reach the set point temperature and stable at temperature near about
controller set temperature.
Ÿ
When temperature of the master and UUC (Unit under calibration) are stable record the readings of master
sensor.
Ÿ
Compare the UUC reading with the master's reading & find out the error by comparison method.
Ÿ
Reset the controller and / or repeat the calibration for another calibration point or for another sensor.
Ÿ
When the calibration is complete, reset the controller to 0°C & wait until the unit has cooled to below 100°C,
before moving the 'CALsys 1700 to new location the 'CALsys 1700' must be cooled below 100°C before it can
be put back into its carrying case.
Ÿ
NOTE :
Always use a reference IR thermometer for comparison calibration method.3
[!] Warning
: Do not exceed the maximum temperature above 1700°C.
