BRIEF INFORMATION ON MEASUREMENT CATEGORIES
Measurement Category IV is applicable to test and measuring circuits connected at
the source of the building’s low-voltage MAINS installation. Examples are
measurements on devices installed before the main fuse or circuit breaker in the
building installation.
Measurement Category III is applicable to test and measuring circuits connected to
the distribution part of the building’s low-voltage MAINS installation. Examples are
measurements on distribution boards (including secondary meters), circuit-breakers,
cables, bus-bars, junction boxes, switches, socket-outlets, stationary motors in the
fixed installation, and equipment for industrial use.
Measurement Category II is applicable to test and measuring circuits connected
directly to utilization points (socket outlets and similar points) of the low-voltage MAINS
installation. Examples are measurements on MAINS CIRCUITS of household
appliances, portable tools and similar equipment.

AC Voltage, DC Voltage, DC+AC Voltage, & Hz Line Level Frequency
In AC Voltage, press SELECT button momentarily to toggle between AC and dBm. In
DC Voltage, press SELECT button momentarily to toggle between DC, and DC+AC. In
mV Voltage, press SELECT button momentarily to select DC, AC, or DC+AC. The new
settings will be saved automatically to the non-volatile memory as power up default. In
DCV and DCmV, press 500000 button momentarily to toggle between 4-4/5 digits and
5-4/5 digits readings. In voltage or current functions, press the Hz push button
momentarily to activate or to exit Line Level Frequency measuring function. Line Level
Frequency measuring function is designed especially for noisy electrical high voltage
signals.
Note: In dBm function, power up default reference impedance will be displayed for 1
second before displaying the dBm readings. Press dBm- (RANGE) button
momentary to select different reference impedance of 4, 8, 16, 32, 50, 75, 93, 110,
125, 135, 150, 200, 250, 300, 500, 600, 800, 900, 1000, up to 1200. The new
impedance value will be saved automatically to the non-volatile memory as power up
default.
5
Note: Line Level Frequency measuring function input sensitivity varies automatically
with voltage (or current) function range selected. The lower the measuring range the
higher the sensitivity. That is, mV function has the highest and the 1000V range has
the lowest as in voltage function ranges. It is recommended to first measure the signal
voltage (or current) level then activate the Hz function in that voltage (or current) range
to automatically get the most appropriate trigger level. When activated from voltage
function, you can also press the RANGE button momentarily to select another trigger
level range manually. The analog bargraph pointer will point at the selected trigger
level range scale 1, 2, 3, or 4. If the Hz reading is unstable, select lower sensitivity to
avoid electrical noise. If the reading shows zero, select higher sensitivity.
Hz Logic Level Frequency and % Duty Cycle functions
Press SELECT button momentarily to toggle between Hz and % (duty cycle) readings.
The new setting will be saved automatically to the non-volatile memory as power up
default. Press 500000 button momentarily to toggle between 5 full digits and 6 full digits
Hz readings.
6
Note: Unlike the Line Level Frequency measuring function as previously stated, this
Logic Level Frequency function is set only at the highest input sensitivity for measuring
digital type electronic signals.
T1-T2 Dual Channels Temperature function (Model 859s only)
Press SELECT button momentarily to toggle between C and F readings, and the
new setting will be saved automatically in the non-volatile memory as power up default.
Press T1-T2 (RANGE) button momentarily to select T1, T2, or T1-T2 readings.
Note: Insert the banana plug K-type temperature bead probe Bkp60 (standard
accessory x 1) with correct polarities. Dual channels T1-T2 readings require 2
probes. You can also use a plug adapter Bkb32 (Optional purchase) with banana pins
to K-type socket to adapt other standard K type mini plug temperature probes.
7
Resistance, Continuity functions
Press SELECT button momentarily to toggle between and Continuity functions.
The new setting will be saved automatically to the non-volatile memory as power up
default. Continuity function is convenient for checking wiring connections and operation
of switches. A continuous beep tone indicates a complete wire.
8
NOTE
Using resistance or continuity function in a live circuit will produce false results and
may damage the meter. In many cases the suspected component must be
disconnected from the circuit to obtain an accurate reading.
Capacitance, Diode test function
Press SELECT button momentarily to toggle between Capacitance and
Diode test functions. The new setting will be saved automatically to the non-volatile
memory as power up default.
NOTE
Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load.
Note: Normal forward voltage drop (forward biased) for a good silicon diode is between
0.400V to 0.900V. A reading higher than that indicates a leaky diode (defective). A zero
reading indicates a shorted diode (defective). An OL indicates an open diode
(defective). Reverse the test leads connections (reverse biased) across the diode. The
digital display shows OL if the diode is good. Any other readings indicate the diode is
resistive or shorted (defective).
9
A, mA, A, and %4-20mA Current functions
Insert the red test lead into the correct A/mA or A input jack. Press SELECT button
momentarily to select DC, AC, or DC+AC. The new settings will be saved automatically
to the non-volatile memory as power up default. In DC mA function, neither in AC nor in
DC+AC, press and hold the %4-20mA ( Hz) button for 1 second or more to display
the current digital data in terms of loop current percentage (%) value. It is set at 4mA =
0% (zero) and 20mA = 100% (span) with 0.01% high resolution, which virtually extends
the meters’ capability to test and regulate the externally powered loop current in the
industrial process control applications. The analog bar-graph remains showing the mA
current value to alert the user.
NOTE: When measuring a 3-phase system, special attention should be taken to the
phase-to-phase voltage that is significantly higher than the phase-to-earth voltage. To
avoid exceeding the voltage rating of the protection fuse(s) accidentally, always
consider the phase-to-phase voltage as the working voltage for the protection fuse(s).
