Checking Procedure
WARNING:
Unless otherwise directed, carry out these procedures with the power switch OFF and the
power UNPLUGGED.
n
Verify the electrical integrity of
the heater and sensor
1. Check for a broken heater or sensor
Measure the resistance while at room tem-
perature(15 to 25°C). It should be 8W±10%.
If the resistance exceeds these limits, replace
the tip.
n
Check the grounding line
1. Unplug the connection cord from the station.
2. Measure the resistance value between pin 2
and the tip (both tips).
3. If the value exceeds 2Ω (at room tem-
perature), perform the tip maintenance
described on P.12 of the MODEL FM-202 in-
struction manual. If the value still does not de-
crease, check the connection cord for break-
age.
n
Checking the connection cord
for breakage
1. Insert a set of verified tips in both sides of the
handle.
2. Measure the resistance value between two
pins.
Pin 1 - Pin 3 7~9Ω
Pin 5 - Pin 3 8~10KΩ
Pin 7 - Pin 4 7~9Ω
Pin 8 - Pin 4 8~10KΩ
If the measured value exceeds above values,
replace the MODEL FM-2023.
Measure the resistance across the tip as shown.
