RANGER® 7000 SCALES |
The Ranger 7000 scale is a precision weighing instrument that will provide you with years of service if properly cared for. The Ohaus Ranger 7000 scales are available in capacities from 3000 grams to 60 kilograms.
Modular Design: Ohaus Ranger 7000 scales are composed of two interconnected modules: a Terminal and a Base. Depending on the user’s needs, the unit can be operated with the Terminal either attached to, or remote from, the Base, with a single interconnect cord 2 meter long. An optional tower kit and extended cord are also available as accessories.
Safety notes are marked with signal words and warning symbols. These show safety issues and warnings. Ignoring the safety notes may lead to personal injury, damage to the instrument, malfunctions and false results.

Information |
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.
Verify that the input voltage range printed on the data label and the plug type matches the local AC power to be used.
Only connect models supplied with a grounded power cord to a compatible grounded power receptacle.
Do not position the scale such that it is difficult to disconnect the power cord from the power receptacle.
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
This scale is for indoor use only.
Use the scale in dry locations only.
Do not drop loads on the pan.
Use only approved accessories and peripherals.
Operate the equipment only under ambient conditions specified in these instructions.
Disconnect the equipment from the power supply when cleaning.
Do not operate the equipment in hazardous or unstable environments.
Service should only be performed by authorized personnel.

RANGER® 7000 SCALES |
Refer to the illustrations and instructions below to identify and assemble your Ranger 7000 scale with its components. All components must be assembled before using the scale.
When the Ranger 7000 is delivered, the Terminal is already attached (docked) to the Base. No additional setup is necessary. Refer to the illustrations and instructions below to identify and assemble your Ranger 7000 Scale.
Note: The Terminal is identical for all Ranger 7000 Scale models.
1.Place the Wind Ring in position (R71MHD3, R71MHD6).
2.Place the platform onto the spider.
Avoid excessive vibrations, heat sources, air current, or rapid temperature changes. Allow sufficient space.
Note: Interface cables connect to the terminal. The terminal can be detached and mounted on a wall or positioned on a table separate from the scale.
The Ranger 7000 comes with an AC power cord. Connect the power cord to a suitable grounded electrical outlet and press the ON button on the side of the base (see figure below).

Attention: Allow equipment to warm up for 60 minutes for optimal weighing performance.

The Ranger 7000 scale has 4 interfaces on the back of the terminal:
-RS422: used to communicate with the base
-RS232: used to connect to computer or a printer
-USB host
-USB slave

Used for options
Cable groove
Thread terminal cable along cable coils on bottom of scale.
Or pass cable through groove near release button.
Only scales that have been leveled precisely horizontally provide accurate weighing results. The certified scales have a spirit level to simplify alignment.
Turn the adjustable feet of the scale until the spirit level’s air bubble is inside the inner circle.
The Terminal communicates with the weighing base via the Terminal cable. This cable must be plugged into the Terminal for the Ranger 7000 to display properly. If desired, the Ranger 7000 scale may be operated either with the Terminal attached, or remotely (up to 1.5 meters away).

RANGER® 7000 SCALES |
1.To detach, press both the Release buttons inward (both at the same time) and gently pull the Terminal towards you (outward) until the Terminal is detached. These Release buttons disengage the two hooks holding the Terminal to the Base. A cable is attached to the Terminal. Take care to not damage or disconnect this cable.
2.To reattach the Terminal, press in the two Release buttons and slide the Terminal into the Base until the Terminal hooks click and engage to hold the Terminal in place.

If desired, the Terminal may be mounted to a wall or table using fasteners (not supplied) that are appropriate for the type of mounting surface.

When the Scale is first installed, and when it is moved to another location, it must be calibrated to ensure accurate weighing results.
R71MHD models have built in AutoCal which can calibrate the scale automatically and does not require calibration masses. If preferred, the scale can be manually calibrated with external masses. Have the appropriate calibration masses available before beginning calibration. Refer to the Calibration Section for masses and calibration procedure.
R71MD models can only be manually calibrated with external masses.

Positive Check
Positive check is used to determine when the material added to the scale is within the target range. In this case the UNDER and OVER limits must be positive values. (The OVER limit must be greater than or equal to the UNDER limit.)
Negative Check
Negative check is used to determine when the material removed from the scale is within the target range. In this case the UNDER and OVER limits are both negative values.
The UNDER limit must be greater than or equal to the OVER limit (for example: UNDER= -10/OVER= -15). Place the item to be weighed on the scale and press Tare.
Remove a portion of the item until it is within the ACCEPT range.

Zero Check
Zero check is used when comparing subsequent samples to an initial reference sample. In this case, the UNDER limit must be a negative value and the OVER limit must be a positive value.
