Liebert 610 3.2.11 Meter Calibration Screen

Operation

If the Battery Time screen is displayed while the battery is not discharging, it will display the present

Battery Charge percentage and the results of the previous discharge event.

The Series 610 records information about each discharge event. If your system has the Battery Cycle

Monitor software, this data can be reviewed on the Battery Cycle Monitor screen, as described in

3.2.4 - Status Reports Screens.

3.2.11 Meter Calibration Screen

Go to the Master Menu and move the highlighted cursor to METER CALIBRATION. Press the Select

pad and the Meter Calibration screen is displayed.

The Meter Calibration screen enables a Liebert field-service engineer to adjust the calibration of the

UPS metered functions. Access to these settings is limited by the Security Access control.

NOTE

1. During initial UPS start-up, the Battery Charge will display 100%, even though actual

state of charge may be slightly less. It will normally take three to four days of operation to

completely charge the battery. After the battery is fully charged the first time, Battery

Charge will be an accurate indication of battery status.

2. If Calculated Time Remaining is less than Rated Time Remaining, a battery problem may

be indicated. Battery maintenance personnel should thoroughly examine the battery plant

for factors that may reduce battery performance, such as:

• Battery age

• Excessive battery discharge/recharge cycles

• Bad or weak cells

• Low acid levels in flooded cells

• Loose electrical connections

• Ambient temperature extremes

• Dirty battery jar covers

3. If the battery plant has been thoroughly examined for proper maintenance and condition

and the Calculated value is still less than 80% of Rated value, contact Liebert Global

Services.

!CAUTION

Meter calibrations are factory-set and should not require adjustment. Contact Liebert Global

Services for meter calibration.

!WARNING

Do not attempt to calibrate meters without adequate training. Meter calibration requires

special test equipment, access to test points in sensitive circuitry and exposure to hazardous

voltage.
