4.4 Calibrate the heating clamp
Forbo Siegling recommends calibrating the heating clamp twice a year.
Required tools
– Temperature measuring device (accuracy ± 1 °C)
– Temperature sensor (Fig. 4.4.1) max. diameter 2 mm
The heating clamp must be in start mode to calibrate. See Section 3
Stop
During operation the heating plates on the heating clamp (1) and the inserted splice
guide (2) may reach a temperature of 210 °C. Injury may occur. (Fig. 2.2.1)
– Set the heating parameters if necessary (see Section 4.3).
– Start calibration mode by simultaneously holding down the "+" and "–" buttons.
The heating clamp then emits an audible signal approximately every second. (Fig. 4.4.2)
– Wait until the heating clamp reaches the selected heating temperature and holds steady
(duration approx. 5 minutes). Signal frequency increases to approx. 2–3 times per second.
– Insert the temperature sensor into the hole on the side of the heating plate.
– Compare the temperature of the measuring device to what is indicated on the display
of the heating clamp.
– If there is a discrepancy in the readings, press the "+" or "–" button on the heating clamp
until the external measuring device indicates the correct temperature as set on the
heating clamp.
Note
The temperature is adjusted following each correction with a slight time lag.
– Save the setting by pressing the "COnFIRM" button.
The heating clamp is now in start mode again.
– Switch the device off by holding down the "On/OFF" button or continue working.
