OPERATING INSTRUCTIONS!
!
The Bartol “Mag-Probe" is an Instrument for
sensing magnetic fields.!
!
CAUTION: Damage may result if the "Mag-
Probe" Is dropped.!
General applications!
All voltages (AC & DC)!
Solenoids, Solenoid valves, Relays, Reed
relays, Coils, Rotary solenoids, Stepper
switches, Detecting residual magnetism,
Coils, Transient current pulses, Identifying
North & South poles, etc.!
The white magnetic shield on the “Mag-
Probe’s" tip reduces the chance of
magnetic fields turning it on during
storage and must be removed before
using. Replace the magnetic shield after
using.!
!
DO NOT STORE THE “MAG-PROBE" NEAR A
PERMANENT MAGNET OR MAGNETIC FIELD.!
!
A “Mag-Probe" will not detect devices
enclosed in a magnetic shield. (most
devices aren’t shielded.)!
!
You may self test the “Mag-Probe" with the
High/Low sensitivity ring supplied with each
unit.!
!
TESTING AC & DC DEVICES WITHOUT!
USING THE HIGH/LOW SENSITIVITY RING!
1. Hold the “Mag-Probe" as shown in
figure 2."
!
2. Place the tip close to or on the shaft that
projects through the device’s coil."
!
3. Observe the LED in the “Mag-Probe’s"
handle."
!
4. If the LED is on,the solenoid or relay is
energized."
!
5. If the LED is off, the solenoid or relay is
de-energized."
!
6. If the LED turns on and off, and flow
through the solenoid valve under test is
not interrupted, or power through a
relay’s contacts don’t turn on and off, a
mechanical failure has occurred. "
!
7. If the LED remains off during machine
operation, two possible problems exist:!
A. No power to the solenoid or relay.!
B. An open coil"
To locate the problem, first test the
power source, then the solenoid or
relay coil."
!
8. If transit pulses are suspected, hold the
Probe tip close to or on the solenoid or
relay and observe the LED during a
machine cycle. If transit pulses are
present during the time the solenoid or
relay should be off, the LED will flash on
and off.!
"
With a little practice, you’ll know when to
use the high/low sensitivity ring in order to
test sub-miniature and smaller devices.!
!
If you need the added sensitivity, install the
high/low sensitivity ring according to the
following instructions.!
