Using the Meter
Display Hold
During measurement, press
reading on the display. Press again to release the hold.
Manual Mode
• The default range in voltage and resistance modes is
auto. To switch to manual range, press "RAN" and
the display switches to manual mode. Each press of the
button increases the range and returns to the lowest
range when pressed in the highest range.
• Hold "RAN" to switch back to auto-range.
Note:
In current mode, manual is only mode available.In
frequency and capacitance modes, only auto-range is
available.
Switching Between Functions
• When the meter is in voltage mode, press "FUNC" to
switch between DC and AC voltage.
• When the meter is in resistance/continuity/capacitance/
diode mode, press "FUNC" to switch between them.
• When the meter is in temperature mode, press "FUNC"
to switch between Fahrenheit and Celsius units.

will stay on for 15 seconds before it automatically turns
off.
• To turn off the backlight manually, hold
• When the meter is in current mode, turning on the
backlight will also activate the worklight, making it easier
to use the clamp in dark areas.
Note:
• The meter uses an LED for a backlight; even though the
backlight is set to turn off after 15 seconds, use only when
necessary to conserve battery life.
Auto Power Off

itself off to conserve battery life.
• To turn the meter back on after auto off, press "FUNC".
• To disable auto power off, hold "FUNC" while turning the
meter on.
Measurement Preparation
• Make sure that when measuring current, the current
being measured does not exceed the maximum rated
current. This can cause overheating and damage the
meter.
• When measuring in manual range and the value to be
measured is unknown, start in the highest range and
adjust the range as needed.
• Make sure to turn the rotary switch to the proper position
before connecting the leads to a circuit.
• When connecting to a circuit, connect the black lead
(COM jack) first before connecting the red lead (INPUT
jack). Remove the leads in the opposite order when
finished.
