Safety Precautions
CAUTION: Read all safety warnings before installing, making connections, or servicing this
equipment. Failure to comply with these warnings could result in personal injury and/or property
damage. Retain all instructions for future reference.
Before connecting power, verify that the equipment’s input voltage range and plug type are
compatible with the local AC mains power supply.
Do not position the equipment such that it is difficult to reach the power connection.
Only connect the power cord to a compatible grounded electrical outlet.
Only use a power cord with a rating that exceeds the specifications on the equipment label. (Only
for i-DT33P)
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
Operate the equipment only under ambient conditions specified in these instructions.
The equipment is for indoor use only.
Do not operate the equipment in hazardous or unstable environments.
Do not allow liquids to enter the equipment.
Use only approved accessories and peripherals.
Disconnect the equipment from the power supply when cleaning.
Service should only be performed by authorized personnel.
WARNING: Never work in an environment subject to explosion hazards! The housing of the instrument
is not gas tight. (Explosion hazard due to spark formation, corrosion caused by the ingress of gases).
WARNING: Electrical shock hazards exist within the housing. The housing should only be opened by
authorized and qualified personnel. Remove all power connections to the unit before opening.
1.2. Intended Use
This instrument is intended for use in laboratories, pharmacies, schools, businesses and light industry. It must

Note: The lead-acid battery will charge automatically while connecting to the power supply. When charging, the
battery level indicator increases or decreases in one grid, two grids, three grids and four grids. The battery level
indicator will disappear when the battery is fully charged.
While operating on battery, the battery symbol indicates the battery status:
Battery 5%~25% remaining
Battery 25%~50% remaining
Battery 50%~75% remaining
Battery 75%~100% remaining
Attention: Before using the indicator for the first time, the internal rechargeable battery should be
fully charged for up to 12 hours. The indicator can be operated during the charging process. The
battery is protected against overcharging and the indicator can remain connected to the AC power
line.
CAUTION: BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED OHAUS SERVICE
DEALER. RISK OF EXPLOSION CAN OCCUR IF THE RECHARGEABLE BATTERY IS

Defender 3000 Indicators EN-13
2.3.2 EasyConnectTM Indicator
To connect an OHAUS EasyConnectTM scale base to an i-DT33P or an i-DT33XW EasyConnectTM indicator,
plug the base's connector into the external load cell connector located at the back (i-DT33P) or bottom (i-
DT33XW) of the indicator. Then rotate the base connector’s locking ring in the direction of the arrows
demonstrated below.
Note: For connecting bases which do not support EasyConnectTM to an EasyConnectTM indicator, contact an
authorized OHAUS dealer to obtain a load cell cable gland kit (P/N 30379716) as an accessory.
2.3.3 Non-EasyConnectTM Indicator
To connect a non-EasyConnectTM scale base to an i-DT33P or an i-DT33XW non-EasyConnectTM indicator,
follow the instruction in Open the Housing section to open the housing first before proceeding.
Note: For connecting EasyConnectTM bases to a non-EasyConnectTM indicator, contact an authorized OHAUS
dealer to obtain a load cell cable gland kit (P/N 30427858) as an accessory.
2.3.3.1 i-DT33P
1. After opening the housing, release the load cell connector (circled) on the rear of the indicator and then
pass the load cell cable through it.
Figure 2-1 i-DT33P
Figure 2-2 i-DT33XW

EN-14 Defender 3000 Indicators
2. Connect all the cables on the load cell cable to the load cell terminal block on the mainboard (circled).
Please refer to the Load Cell Terminal Block section for details of the connections.
2.3.3.2 i-DT33XW
1. After opening the housing, unplug the battery connectors (circled) and take out the battery.

Defender 3000 Indicators EN-15
2. Unscrew the two screws on the sealing cover (circled), take out the cover, and then take out the first layer
of the built-in housing.
3. Release the load cell connector (circled) on the bottom of the indicator and then pass the load cell cable
through it.
4. Connect all the cables on the load cell cable to the load cell terminal block on the mainboard (circled).
Please refer to the Load Cell Terminal Block section for details of the connections.

EN-16 Defender 3000 Indicators
2.3.3.3 Load Cell Terminal Block
Proceed with the previous section, to connect the load cell terminal block, first locate it on the mainboard
following the instruction in the previous two sections for the two models.
After finding the load cell terminal block, check table 2-1 for the definition of each terminal screw connection
and make connections based on it. Please note that when using four-wire load cells, jumpers (the two short
wires supplied) must be placed between the +Excitation (+EXE) and +Sense (+SEN) terminals and between
the -Excitation (-EXE) and -Sense (-SEN) terminals.
The i-DT33P and i-DT33XW indicators are designed to support both 2mV/V and 3mV/V load cells from the
same circuitry. A load cell output rating selection jumper is not required.
2.3.3.4 Installing the Ferrite Core
In order to meet certain electrical noise emission limits and to protect i-DT33P and i-DT33XW from external
influences, it is necessary to install a ferrite core on the load cell cable connected to the indicator. The ferrite
core is supplied.
To install it, simply route the cable through the center of the core. Either the complete cable or the individual
wires can be wrapped through it.
