Checking Procedure
WARNING:
Unless otherwise directed, carry out these procedures with the power switch OFF and the power UNPLUGGED.
1. Check for a broken heater or sensor
Verify the electrical integrity of the heater
and sensor.
Measure the resistance of the heater and
sensor while at room temperature (15 to 25
°C.; 59 to 77°F.). It should be 8Ω ±10%. If the
resistance exceeds these limits, replace the tip.
1. Unplug the connection cord from the station.
2. Measure the resistance value between Pin
2 and the tip.
3. If the value exceeds 2Ω (at room tem-
perature), perform the tip maintenance
described on p.55. If the value still does not
decrease, check the connection cord for
breakage.
1. Remove the soldering tip and the sleeve
assembly.
2. Turn the front piece of the MODEL FM-2025
counterclockwise and remove the cover.
3. Measure the resistance values between the
connector and the lead wires at the socket
as follows:
Pin 1 – Red
Pin 2 – Green
Pin 3 – Black
Pin 5 – White
If any value exceeds 0Ω or is ∞, replace the
MODEL FM-2025.
1. Unplug the power cord from the power
receptacle.
2. Remove the fuse holder.
3. Replace the fuse.
4. Put the fuse holder back in place.
