used in a manner not specified by the manufacturer, the protection provided by the
meter may be impaired.
Observe proper safety precautions when working with voltages above 30 Vrms, 42.4
Vpeak, or 60 VDC. These voltage levels pose a potential shock hazard to the user.
Disconnect the test leads from the test points before changing functions. Do not
expose this product to rain or moisture. The meter is intended only for indoor use.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test
probe assembly, where applicable) that indicate the limits of safe access of the hand-
held parts during measurements. Inspect lead wires, connectors, and probes for
damaged insulation or exposed metal periodically. If any defects are found, replace
them immediately. Only use the test probe assembly provided with the meter or a UL
Listed test probe assembly to the same meter ratings or better. Optional offer premium
test probe assembly using silicone lead wire insulation, at agent’s discretion, is
equipped with white inner insulation layers as wear indicators. Replace them
immediately if any of the white layers has become visible.
The meter meets IEC/EN/BSEN/CSA_C22.2_No./UL standards of 61010-1 Ed. 3.1 and
61010-2-033 Ed. 2.0 to Measurement Categories CAT III 1000V and CAT IV 600V. The
accompanied test probe assembly meets IEC/EN/BSEN/CSA_C22.2_No./UL
standards of 61010-031 Ed. 2.0 to the same meter ratings or better. The 61010-031

4) OPERATION
Note: Before and after hazardous voltage measurements, test the voltage function on
a known source such as line voltage to determine proper meter functioning
4
ACV; Line-level Hz (Models 2807 & 2805 only)
Inputs are made via the terminals COM/V. Startup defaults to ACV Function. Press the
SELECT button momentarily to select the Line-level Hz function.
Note: Input sensitivity varies automatically with the function range selected while
activating the Hz function. 6V function range has the highest and the 1000V range has
the lowest. When activated, the trigger voltage range will be displayed right before the
Hz readings start. Press momentarily the RANGE button can manually select another
trigger voltage range. It is recommended to first measure the signal voltage level and
activate the Hz function in that range to get the most appropriate trigger level. If the Hz
reading becomes unstable, select lower sensitivity to avoid electrical noise. If the
reading shows zero, select higher sensitivity.
EF-Detection of Electric Field (Model 2807 only)
Startup defaults to ACV Function. Press the SELECT button momentarily twice to
select the EF-Detection function. The meter displays “EF-H”, the High sensitivity, when
it is ready. If it is too sensitive for your applications, press the (LEVEL) button
momentarily to toggle to EF-L, the Low sensitivity. The detected Electric Field is
indicated as a series of display bar-segments, backlight flashing, and beep sounds in
proportion to the field strength.

●Non-Contact EF-Detection (NCV): An antenna is located near the top end center of
the meter, which detects the ac electric field surrounding energized conductors. It is
ideal for tracing live wiring connections, locating wiring breakages, and distinguishing
between live and earth connections.
●Probe-Contact EF-Detection (Single-pole): For more precise indications of live
6
wires, such as distinguishing between Live and Ground connections, use one single
test probe to test via terminal COM for direct metal contact-probing to achieve the most
distinctive indications.
DCV; VFD-ACV & Line-level VFD-Hz (Models 2807 & 2805 only)
Inputs are made via the terminals COM/V. Startup defaults to DCV Function. Press the
SELECT button momentarily to select the subject functions in sequence.
Note: VFD-ACV and VFD-Hz are equipped with a digital low-pass filter (DSP) and are
capable of handling VFD (Variable Frequency Drives) signals for fundamental V & Hz
readings. It also improves ACV and Hz reading stability when being used in most
electrically noisy environments.
Note: Input sensitivity varies automatically with the function range selected while
activating the VFD-Hz function. 600V function range has the highest and the 1000V
range has the lowest. When activated, the trigger voltage range will be displayed right
before the Hz readings start. Press momentarily the RANGE button can manually
select another trigger voltage range. It is recommended to first measure the signal
voltage level and activate the Hz function in that range to get the most appropriate
trigger level. If the Hz reading becomes unstable, select lower sensitivity to avoid
electrical noise. If the reading shows zero, select higher sensitivity.
7
DCmV; ACmV; Logic-level Hz (Models 2807 & 2805 only); °C/°F (Model 2807 only)
Inputs are made via the terminals COM/V. Startup defaults to DCmV Function. Press
the SELECT button momentarily to select the subject functions in sequence.
Note:
1) In ACmV function:
8
1-1) ACmV startup defaults to the AC 600.0mV range. Auto-ranging is not available.
Press the RANGE button momentarily to toggle to the AC 60.00mV range for extended
resolution.
1-2) Using the ACmV function in a composite signal beyond the peak levels specified in
the specifications will saturate the respective ranges and produce false results. Instead,
the meter shows OL with both DC & AC icons when the peak value is exceeded in this
regard. Suspected signal levels can be verified with the DCV and ACV functions.
1-3) To measure ACmV signals coupled merely in AC nature when required, it is
recommended to add in series an appropriate DC blocking capacitor in the
measurement loop.
2) In temperature function:
2-1) Be sure to insert the banana-plug type-K temperature bead-probe with correct
polarities. Banana-pins to type-K socket adapter Bkb32 (Optional purchase) can
be used to accept other type-K probes using standard miniature plugs.
2-2) Temperature accuracies assume the meter interior has the same temperature
(isothermal stage) as the ambient, particularly at the plug of the probe being used, for a
correct junction voltage compensation. Allow the meter interior temperature to catch up
with that of the plug after a sudden change in the measuring environment and hence
the ambient temperature. This can take up to an hour, for changes > 5°C, within a low
ventilated sturdy meter housing. The uncompensated temperature differences, if any,
will be reflected as offsets on the meter readings.
2-3) °F selection can be left out as factory calibration default for countries that only
accept metric units.

Resistance; BeepLitTM Continuity; & BeepLitTM Diode
Inputs are made via the test lead terminals COM/. Startup defaults to Resistance.
Press the SELECT button momentarily to select the subject functions in sequence.
◎ BeepLitTM Continuity
This function is having improved convenience for checking wiring connections and
operation of switches. The resistance threshold is being used. A continuous beep
sound together with display backlight flashing indicates a complete wire. Such audible
and visible indications improve continuity readabilities in noisy working environments.
◎ BeepLitTM Diode
●Reading indication: Forward voltage drop (forward-biased) for a good silicon diode
is between 0.400V to 0.900V. A higher reading indicates a leaky diode (defective). A
zero reading indicates a shorted diode (defective). An over-range display indicates an
open diode (defective). Reverse the test leads connections (reverse biased) across the
diode. The digital display shows an over-range if the diode is good. Any other readings
indicate the diode is resistive or shorted (defective).
●BeepPassTM indication (Short-beep):
When the display reading drops across 0.850V, the BeepPassTM indication gives a
short beep sound to signal a Good forward voltage drop of common diodes.
●BeepLitTM indication (Continuity):
