Selecting the Location

Use the scale on a firm, steady surface. Avoid locations with excessive air current, vibrations, heat sources or rapid temperature changes. Allow sufficient space around the scale.

Leveling the Equipment

The Ranger Series has a level indicator as a reminder that the scale should be leveled for accurate weighing. There is a level bubble in a small round window on the front of the scale.
To level the scale, adjust the feet so the bubble is centered in the circle.
Be sure the equipment is level each time its location is changed.
Figure 2-2. Level indicator

Connecting Power

AC power is used to power the scale when battery power is not needed. First, connect the AC power cord (supplied) to the power input jack then connect the AC plug to an electrical outlet.
Figure 2-3A. Connect the power plug to the input jack on the back of scale.

Figure 2-3B. Connect AC power plug to the proper AC supply.

Battery Power:
The scale can be used on AC power immediately. Allow the battery to charge for 12 hours before using the scale on battery power. The Scale will automatically switch to battery operation if there is a power failure or the power cord is removed. With AC power, the scale is constantly charging, so the battery charge indicator (see item 10 in table 3-2) will remain lit. The scale can be operated during charging, and the battery is protected against overcharging.
For maximum operating time, the battery should be charged at room temperature.
During battery operation, the battery symbol indicates the battery charge level remaining. The indicator will automatically turn off when the batteries are fully charged.

TABLE 2-1

Symbol	Charge level
	0 to 10% Remaining
	11 to 40% Remaining
	41 to 70% Remaining
	71 to 100% Remaining

Notes:
When battery symbol blinks fast, approximately 30 minutes working time is left.
When [lo.bat] is displayed, the scale will shut off.
Charging the scale must be performed in a dry environment.

Battery is to be replaced only by an authorized Ohaus service dealer. Risk of explosion can occur if the rechargeable battery is replaced with the wrong type or if it is not properly connected. Dispose of the lead acid battery according to local laws and regulations.

Capacity Label

A label showing the capacity and readability of the scale must be installed near each display. If the Capacity Labels were installed prior to delivery, no further action is needed. If the Capacity Labels were not installed, they have been placed in the packaging material. Affix the labels above the displays as shown in Figure 5-1.
Note: The Capacity Labels will be destroyed upon removal, so only attempt to install them once.

Settings

Before verification and sealing, perform the following steps:

1. Verify that the menu settings meet the local weights and measures regulations.
2. Perform a calibrationю
3. Set the switch to Locked. See figure 5-2.

The Menu Lock switch limits changes to the Cal, Setup, Readout, Unit and Print menus. The switch in type approved models may set some scale settings as required by the approval agency. The switch may be secured using paper seals, wire seals or plastic ties.

Note: When LEGAL FOR TRADE is set to ON (LFT Switch in locked position), the menu settings are affected as follows:
Calibration (C.A.L) menu is not accessible Zero Range setting is locked at 2%.
Stable Range setting is locked at 1d
Auto-Zero Tracking setting is locked at 0.5d
Filter and Units are locked at their current settings
Stable Only is locked On Auto Print/ Continuous is disabled lb: oz is locked Off.

Verification and Sealing

The local weights and measures official or authorized service agent must perform the verification procedure.

Physical Seals
For jurisdictions that use the physical sealing method, the local weights and measures official or authorized service agent must apply a security seal to prevent tampering with the settings. Refer to the illustration below for sealing methods.

Figure 5-2. Sealing

Audit Trail Seal (USA and Canada only)
For jurisdictions that use the audit trail sealing method, the local weights and measures official or authorized service agent must record the current configuration and calibration event counter values at the time of sealing. These values will be compared to values found during a future inspection.
Note: A change to an event counter value is equivalent to breaking a physical seal.
The audit trail uses two event counters to record changes to configuration and calibration settings.

• The configuration event counter (CFG) will index by 1 when exiting the menu if one or more of the following menu settings are changed: Zero Range, Stable Range, Auto Zero Tracking (AZT), Units (kg, g, oz, lb or lb: oz) or Stable Only.
• The calibration event counter (CAL) will index by 1 when exiting the menu if a Span Calibration or GEO setting change is made. Note that the counter only indexes once, even if several settings are changed.
  The event counters can be viewed by pressing and holding the MENU button. While the button is held, the display will show MENU followed by Audit.
  
  Release the button when Audit is displayed to view the audit trail information.
  
  The audit trail information is displayed in the format CFGxxx and CALxxx.
  
  The scale then returns to normal operation
  

MAINTENANCE

Troubleshooting

The following table lists common problems and possible causes and remedies.
If the problem persists, contact OHAUS or your authorized dealer.

TABLE 6-1

Symptom	Possible Cause	Remedy
Cannot turn on	No power to scale	Verify connections and voltage
Poor accuracy	Improper calibration Unstable environment	Perform calibration Move scale to suitable location
Cannot calibrate	LFT locked	See chapter 5 for information
Cannot access mode	Mode not enabled	Enter menu and enable mode
Cannot access unit	Unit not enabled	Enter menu and enable unit
Battery icon flashing	Low Battery error	Connect scale to AC power and charge the battery
	Power On Error	Weight reading exceeds Power On Zero limit
	Power On Error	Weight reading below Power On Zero limit.
	Over Range Error	Weight reading exceeds Overload limit
	Under Range Error	Weight reading below Underload limit
	Tare out of range	Adjust tare value to be within range
	Display overflow	Weight exceeds 6 digits
	Calibration data error	Calibration data not present
	Busy	Displayed during tare setting, zero setting, printing
	Action not allowed	Function not executed
	Calibration error Unstable environment Incorrect calibration weight	Calibration value outside allowed limits Move the scale to suitable location Use correct calibration weight
	Low reference weight warning	Increase reference weight
	Unacceptable reference weight	Reference weight too small. Weight on the pan is too small to define a valid reference weight. Increase reference weight.
	Gross and net weights cannot be accumulated together	Only accumulate gross or net weights (only works in LFT)
Battery fails to charge fully	Battery is defective	Have battery replaced by Ohaus authorized service dealer.
