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-Ω (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 1200Ω . The
new impedance value will be saved automatically to the non-volatile memory as
power up default. 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.
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 ºC and ºF 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. Ω Resistance, Continuity functions
Press SELECT button momentarily to toggle between Ω 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
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).
μA, mA, A, and %4-20mA Current functions
Insert the red test lead into the correct μA/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).
PC-COMM computer interface capabilities
The instrument equips with an optical isolated interface port at the meter
back for data communication. Optional purchase PC interface kit BRUA-85Xa (BC-
85Xa RS232C optical adapter cable + BS85X software CD + BUA-2303 USB-to-Serial
adaptor) is required to connect the meter to the PC computer. The Bs85x Data

jacks when other
function (like voltage function) is selected.
Intelligent Auto Power Off (APO)
The Intelligent Auto Power Off (APO) mode turns the meter off automatically to
extend battery life after approximately 17 minutes of no activities.
Activities are specified as: 1) Rotary switch or push button operations, and
2) Significant measuring readings of above 10% of range or non-OL Ω readings.
In other words, the meter will intelligently avoid entering the APO mode when
it is under normal measurements. To wake up the meter from APO, press the
RECORD button momentarily or turn the rotary switch to
the OFF position and then turn back on again. Always turn the rotary switch to
the OFF position when the meter is not in use.
Disabling Auto Power Off

Off (APO) feature.
MAINTENANCE
NOTE
To avoid electrical shock, disconnect the meter from any circuit, remove
the test leads from the input jacks and turn OFF the meter before opening the
case. Do not operate with open case. Install only the same type of fuse or
equivalent
Calibration
Periodic calibration at intervals of one year is recommended to maintain meter
accuracy. Accuracy is specified for a period of one year after calibration.
If self-diagnostic message “rE-O” is being displayed while powering on, the
meter is re-organizing internal parameters. Do not switch off the meter then,
and it will be back
to normal measurement shortly. However, if self-diagnostic message “C_Er” is
being displayed while powering on, some meter ranges might be largely out of
specifications.
To avoid mis-leading measurements, stop using the meter and send it for re-
calibration. Refer to the LIMITED WARRANTY section for obtaining warranty or
repairing service.
Trouble Shooting
If the instrument fails to operate, check battery, fuses, leads, etc., and
replace as necessary. Double check operating procedure as described in this
user’s manual. If the instrument voltage-resistance input terminal has
subjected to high voltage transient (caused by lightning or switching surge to
the system) by accident or abnormal conditions of operation, the series
fusible resistors will be blown off (become high impedance) like fuses to
protect the user and the instrument. Most measuring functions through this
terminal will then be open circuit. The series fusible resistors and the spark
gaps should then be replaced by qualified technician. Refer to the LIMITED
WARRANTY section for obtaining warranty or repairing service.
Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do not use
abrasives or solvents. If the meter is not to be used for periods of longer
than 60 days, remove the battery and store it separately.
