Hi Voltage Indicator
In any VAC/VDC range, when you touch a voltage
greater than 30V, the beeper will beep and the red Hi-
V LED will blink. BE CAREFUL!
Capacitance
For motor-start and motor-run capacitors.
Disconnect the capacitor from power first. Short the
terminals to discharge the capacitor. Disconnect any
resistors that might be between the terminals of the
capacitor.
MAX and Data HOLD
Press MAX to store highest reading on the display.
Press MAX again to return display to real-time read-
ing. Press HOLD to hold current data on the display.
Silicone Leads
Because the wire insulation is silicone the leads
will stay flexible in cold weather and will not melt if
bumped by a soldering iron.
Safe One-Handed Testing
When testing electrical circuits with two hands,
there is a risk that a careless mis-
take may complete a circuit
through your body and potentially
cause death or injury.
First disconnect the top half of
red test lead and plug tip directly
into Volts jack. Plug alligator clip
lead into the COM jack (you may
need to use a lead with tip
removed as an extension). Then
clip the alligator lead to one test
point.
With the black alligator lead
secured, you’re now free to hold
the meter with one hand and
touch other test points with the
probe tip.
Modular Expandability
Modular expandability is the ability for accessory
heads and meters to change configurations to match
the various needs of an HVAC/R technician.
Accessory heads (the sensors) send a mV signal,
which represents the value of the parameter being
tested. Heads can attach directly to the top of a Stick
meter, DL3 data logger, or EHDL1. They can also
plug into any meter with mV ranges using ADLS2
leads.
Accessory Heads
Accessory heads, like the included ACH4, are the
sensors of multiple parameters measured by techni-
cians every day. They plug into a mV range (depend-
ing on the head) of a multimeter. The multimeter will
display whatever the head is measuring. Instead of
having to purchase and carry a separate instrument
for each parameter, a technician can use multiple
heads and a single multimeter to do the job.
Here are four of the many heads available:
AAV3 Air Velocity and Temperature
ADMN2 Dual-Port Manometer
AVG2 Digital Vacuum Gauge
AOX2 Combustion Check
