WARNING

To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. To
avoid electrical shock hazard, observe the proper safety precautions when working with
voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard
to the user. Do not touch test lead tips or the circuit being tested while power is applied to
the circuit being measured. Keep your fingers behind the finger guards of the test leads
during measurement. Inspect test leads, connectors, and probes for damaged insulation or
exposed metal before using the instrument. If any defects are found, replace them
immediately. Do not measure any current that exceeds the current rating of the protection
fuse. Do not attempt a current measurement to any circuit where the open circuit voltage is
above the protection fuse voltage rating. Suspected open circuit voltage should be checked
with voltage functions. Never attempt a voltage measurement with the test lead inserted into
the A/mA or A input jack. Only replace the blown fuse with the proper rating as specified in
this manual.

CAUTION

Disconnect the test leads from the test points before changing functions. Always set the
instrument to the highest range and work downward for an unknown value when using
manual ranging mode.

Average sensing RMS calibrated

RMS (Root-Mean-Square) is the term used to describe the effective or equivalent DC value
of an AC signal. Most digital multimeters use average sensing RMS calibrated technique to
measure RMS values of AC signals. This technique is to obtain the average value by
rectifying and filtering the AC signal. The average value is then scaled upward (calibrated)
to read the RMS value of a sine wave. In measuring pure sinusoidal waveform, this
technique is fast, accurate and cost effective. In measuring non-sinusoidal waveforms,
however, significant errors can be introduced because of different scaling factors relating
average to RMS values.

True RMS

True RMS is a term which identifies a DMM that responds accurately to the effective RMS
value regardless of the waveforms such as: square, sawtooth, triangle, pulse trains, spikes,
as well as distorted waveforms with the presence of harmonics. Harmonics may cause :

1)Overheated transformers, generators and motors to burn out faster than normal

2)Circuit breakers to trip prematurely

3)Fuses to blow

4)Neutrals to overheat due to the triplen harmonics present on the neutral

5)Bus bars and electrical panels to vibrate

Crest Factor

Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS value, and
is commonly used to define the dynamic range of a True RMS DMM. A pure sinusoidal
waveform has a Crest Factor of 1.4. A badly distorted sinusoidal waveform normally has a
much higher Crest Factor.

4) OPERATION

CAUTION

Before and after hazardous voltage measurements, test the voltage function on a known
source such as line voltage to determine proper meter functioning.

AutoCheckTMmode (TBM525 & TBM829 only)

This innovative AutoCheckTMfeature automatically selects measurement function of DCV,
ACV or Resistance () based on the input via the test leads.

●With no input, the meter displays “Auto” when it is ready.

●With no voltage signal but a resistance below 60M is present, the meter displays the

resistance value. When below “Audible Threshold“ is present, the meter further gives a
continuity beep tone.

●When a signal above the threshold of 1.5V DC or 3V AC up to the rated 1000V is present,

the meter displays the voltage value in appropriate DC or AC, whichever larger in peak

5

magnitude.

Note:
*Range-Lock and Function-Lock Feature: When a measurement reading is being
displayed in AutoCheckTMmode, press the RANGE or SELECT button momentarily 1 time
can lock the range or function it was in. Press the button momentarily repeatedly to step
through the ranges or functions.

*As Hazardous-Alert: When making resistance measurements in AutoCheckTMmode, an
unexpected display of voltage readings alerts you that the object under test is being
energized.

*Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent
hard signals, which confuse common multimeter voltage measurements. Our AutoCheck

TM

mode provides low (ramp-up) input impedance (approx. 3kΩ at low voltage) to drain ghost

voltages leaving mainly hard signal values on meter readings. It is an invaluable feature for
precise indication of hard signals, such as distinguishing between hot and open wires (to
ground) in electrical installation applications.

WARNING:

AutoCheckTM mode input impedance increases abruptly from initial 3kΩ to a few hundred
kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being

6

in such low impedance mode. Peak initial load current, while probing 1000VAC for

example, can be up to 471mA (1000V x 1.414 / 3kΩ), decreasing abruptly to approx. 3.1mA
(1000V x 1.414 / 460kΩ) within a fraction of a second. Do not use AutoCheckTMmode on

circuits that could be damaged by such low input impedance. Instead, use rotary selector
or high input impedance voltage modes to minimize loading for such circuits.

5) MAINTENANCE

WARNING

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

16

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 re­organizing internal parameters. Do not switch off the meter, 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 mis­leading measurements, stop using the meter and send it for re-calibration. 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

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.
