 Checking Procedure

WARNING:

Unless otherwise directed, carry out these procedures with the power switch OFF and the power UNPLUGGED.

■

Check for a broken heater or
sensor

1. Check for a broken heater or sensor

Measure the resistance
across this position.

1Y100CB3

T7-D24

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 8

Ω ±

10%. If the

resistance exceeds these limits, replace the tip.

■

Check the grounding line

1. Unplug the connection cord from the station.
2. Measure the resistance value between Pin 2

and the tip.

3. If the value exceeds 2

Ω

 (at room temperature),

perform the tip maintenance described on P.12.
If the value still does not decrease, check the
connection cord for breakage.

■

 Checking the connection cord

for breakage

1. Remove the soldering tip and the sleeve

assembly.

2. Turn the front piece of the FM-2021 clockwise

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 0

Ω

, replace the FM-2021.
