Resistance measuring
Heating foil in handle (2)
Switch OFF the handle heating 1.
Measure the resistance between the pin at the out-
side of the heater switch and the connection at the
front of the sleeve of the second handle.
Resistance 1-2 Ohm (at approx. 20°C)
Tank (038.114.070) must be replaced completely if
resistance is incorrect.
Heating foil in tubular handle (3)
Measure the resistance between both pin contacts
of the tubular handle.
Resistance approx. 5 Ohm (at approx. 20°C)
Tubular handle (038.310.030) must be replaced if
resistance is incorrect.
Tools
Conductivity tester or multi meter to test electri-
cal resistance and conductivity.
