Safety Guidelines
General Guideline
CAUTION
Make sure that the voltage input level does not
exceed DC330V (for GBM-3300).
DC80.8V (for GBM-3080).
AC voltage input is strictly prohibited.
Do not place any heavy object on the
instrument.
Avoid severe impact or rough handling that can
lead to damaging the instrument.
Do not discharge static electricity to the
instrument.
Use only mating connectors, not bare wires, for
the terminals.
Do not perform measurement at the source of a
low-voltage installation or at building
installations (Note below).
Do not disassemble the instrument unless you
are qualified as service personnel.
Remove all test leads before disconnecting the
mains power cord from the socket.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
The device should be placed in a place where
the plug connected to it can be removed easily.
(Note) EN 61010-1:2010 specifies the measurement categories and
their requirements as follows. The GBM-3000 Series doesn’t fall
under category II, III or IV.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.

Power Supply
WARNING
AC Input voltage: 100-240 VAC 50/60Hz
The power supply voltage should not fluctuate
more than 10%.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Cleaning the
Instrument
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity:
< 30°C: < 80%RH(non-condensing);
30°C~40°C: <70%RH(non-condensing);
>40°C: <50%RH (non-condensing)
Altitude: <2000m
(Note) EN 61010-1:2010 specifies the pollution degrees and their
requirements as follows. The GBM-3000 SERIES falls under degree
2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of
dielectric strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the unit in the United Kingdom, make sure the power
cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Characteristics
Thank you for purchasing the GBM-3300/ GBM-3080 battery meter.
The GBM-3000 series uses 32-bit ARM microprocessor control and
3.5-inch true color LCD display.
It can be used to test resistance ranging from 0.0001mΩ to 3.2kΩ
and test DC voltage ranging from 0.00001V to 300.000V. The GBM-
3000 series has several characteristics such as high accuracy, high
resolution and ultra-high speed measurement with 0.5% resistance
accuracy and 0.01% voltage accuracy and up to measurement speed
of 60 times per second.
Comparator function and Handler (PLC) interface can be used to
output HIGH/ IN/ LOW resistance signal and HIGH/ IN/ LOW
voltage signal. It can meet the require of automatic sorting system
to complete the fully automated assembly line test, while enhance
IO signal to drive power relays and signal relays directly.
The built-in RS-232C interface and USB interface can be used for
remote control and data acquisition and analysis.

Including slow, medium, fast and exfast test.
When all channels opened and measurement in
manual mode. 4 times per second for slow
speed mode; 11 times per second for medium
speed mode; 25 times per second for fast speed
mode; 60 times per second for exfast mode.
2 trigger modes, including internal and external.
Calibration function
Short circuit clearing for full ranges is to
eliminate the influence of lead resistance.
System configuration, including data retention
function, alarm setting, keyboard lock function
and administrator and user accounts which
allows to set a password for administrator
Comparator function (Sorting function),
including RHI/RNG/RLO output,
VHI/VNG/VLO output and total NG/OK
output.
Comparison method:
Absolute tolerance ± TOL sorting: The absolute
deviation of the measured value from the
nominal value is compared with the limit of
each range.

GBM-3080/3300 User Manual
14
Percent tolerance %TOL sorting: The percentage
deviation of the measured value from the
nominal value is compared with the limit of
each range.
Sequential sorting: The measured value is
directly compared with the upper and lower
limits setting.
Interface
RS-232 / USB remote control:
Support up to maximum 115200bps serial
transmission rate, compatible SCPI agreement
and ASCII transmission.
Handler I/O interface
All isolation with opt coupler. It equipped with
built-in input and output port to pull up
resistance.
