Specialized Tool
l
Analog AC Clamp-on Ammeter or Digital Clamp Meter with True RMS current meas-
urement capability (recommend the Fluke 289 True RMS multimeter or equivalent).
Procedure
Read the entire procedure before beginning.
TIP
: You may find it difficult to read the AC current reading while also walking on the
treadmill. You may need a second person to read the AC clamp meter while per-
forming this test. Or, if using a DMM with clamp probe, you can use extra-long test
leads (approx. 1.5 m) that will allow you to set the DMM on the dash while performing
the test.
1. Clean the belt and deck surfaces.
2. Remove the treadmill hood cover.
3. Place the AC clamp probe over the brown (hot or line) wire between the AC. input
module (or AC. power cord) and the circuit breaker ON/OFF switch.
4. Start a manual workout and set the treadmill speed to 8 mph (13 kph) and 0% incline.
Walk on the treadmill for a minimum of 10 sec and read the AC average (True RMS)
input current. Typical AC. average current for a good condition running belt/deck is
between 8 to 12 amps on 120

machines (4 to 6 amps on 240 VAC machines).
A new belt/deck may read less current draw. Note that during foot plants, you could
