OPERATION
NOTE: Sections A-F apply to the Pro48 multi-function irrigation
tester by itself. Sections G and H will incorporate the Pro210F
advanced tone probe.
A. Battery Test
1. Connect the red and black alligator clips together.
2. Place the top switch to the SOLENOID ACTIVATE mode.
3. If the batteries are good (at least 15 volts) the SHORT LED
will turn on. If batteries are weak, the short light may only stay
on briefly or not at all.
B. Clock Test
1. Place the Pro48 in the OFF mode. Connect the red alligator
clip to the station wire to be tested and the black alligator clip
to the common wire.
2. Turn on the clock station to be tested.
3. If the proper voltage is detected, the CLOCK 24V AC LED will
turn on.
C. Activating/Testing a Solenoid at the Clock
NOTE: The Pro48 cannot activate solenoids that run on AC
voltage only (i.e., capacitor coupled solenoids).
1. To activate solenoids from the clock, turn the clock off and
place the top switch of the Pro48 to OFF.
2. Connect the Pro48 by attaching the red lead to the station wire
and the black lead to the common wire.
3. Place the side sliding switch to ACTIVATE and the top switch
to SOLENOID.
4. The solenoid under test should activate and the GOOD LED
(see display on the front of the Pro48) should turn on.
If the solenoid does not activate, one of the following conditions
may exist:
• Short: SHORT LED is on (< 10 Ohm)
• Open: OPEN LED is on (> 200 Ohm)
5. The Pro48 must be turned off to reset the unit after the solenoid
is activated.
