Worklight LED ON/OFF
To turn the light on and off, press the button.
HOLD Key
Data Hold Function - Freezes the value on the dis-
play. Press the “HOLD” button to freeze the reading.
The reading will be held regardless of subsequent
variation in input. HOLD is displayed with the read-
ing. To exit Data Hold mode, press the HOLD button
again.
CAUTION
The Data Hold readings are re-
leased when the meter enters Sleep
Mode.
Sleep Mode
The clamp meter is automatically powered off in
about 20 min after the last Rotary Dial or button
operation. To reset, rotate the Rotary Dial to OFF.
If the display is still blank when a new Rotary Dial
setting is selected, replace the batteries.
The sleep mode is disabled when the MIN/MAX
function is selected.
The clamp meter does use battery power in sleep
mode. Be sure to switch the tool to OFF to conserve
battery power.
Non-Contact Voltage Detection (NCVD)
DANGER
The LED may not be displayed due
to installation condition of electri-
cal circuit or equipment. Never touch the circuit
under test to avoid possible danger even if the
LED for NCVD is not displayed.
Check the functionality of LED on a well-known
power supply prior to measure-
ment. When the LED doesn’t
light up, do not make mea-
surement.
NCVD indication is affected by
external voltage, and how the
meter is held or placed.
When the meter is on in any
function, the non-contact volt-
age detector will indicate with a
Red LED on the display when
an electric field exceeding 90V is
detected. Place the edge of the
jaw labeled “Voltage Detector”
near the electric field.
Over-flow indication
Any time the input exceeds the measuring range “OL”
or “-OL” is displayed.
CAUTION
Clamp the jaws around the conduc-
tor under test and press the MIN/
MAX button after an appropriate range is se
-
lected by Auto-ranging function. ZERO and Hz
keys are disabled while MIN/MAX Function is
active.
MIN/MAX Function
The MIN/MAX function can be used
during measurements of AC or DC
current, AC or DC voltage, Tempera-
ture (2236-20 only), uA DC (2236-20
only), and Resistance. The MIN/MAX
function does not work in the Capaci-
tance or Continuity measurements.
To measure the minimum or maximum
of the function, set the dial to the ap-
propriate dial position and then press
the MIN/MAX button to capture the
maximum reading. Press the MIN/
MAX button again to capture the
minimum reading.
Press the MIN/MAX button to toggle
between minimum or maximum. The
minimum or maximum reading is
displayed and held until the MIN/MAX is turned off
by holding in the MIN/MAX button for 2 seconds or
changing the Rotary Dial position.
CAUTION
Auto-Ranging and MIN/MAX button
are disabled when ZERO function
is in use. ZERO function operates only in AC
Current , DC Current and Capacitance
.
ZERO Function
AC Current / DC Current :
When the LCD
doesn’t read ZERO while the
Jaws are closed, press the
ZERO Button to indicate
ZERO before starting a
measurement. In this case,
the “ZERO” mark appears
on the LCD to indicate the
ZERO Function is activated.
Capacitance
:
Effective
at 40nF Range only. Press
the ZERO Button with the
Test leads opened before
measuring capacitances to
indicate ZERO before start-
ing a measurement.
MAINTENANCE
WARNING
To reduce the risk of injury, always
remove the batteries from the tool
before performing any maintenance. Never disas
-
semble the tool. Contact a MILWAUKEE service
facility for ALL repairs.
Maintaining Tool
Keep your tool in good repair by adopting a regular
maintenance program. After one year, it is recom-
mended to return the tool to a MILWAUKEE service
facility for calibration.
If the tool does not start or operate at full power with
fully charged batteries, clean the contacts on the bat-
tery door. If the tool still does not work properly, return
the tool to a MILWAUKEE service facility for repair.
WARNING
To reduce the risk of personal in-
jury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
