EN-8 BW SERIES COMPACT BENCH SCALE
6. CALIBRATION AND SEALING
6.1 Calibration
For best results, calibrate the scale at regular intervals. Temperature changes,
geographic gravity variations, altitude changes and abuse are few reasons why a
scale may need recalibration.
Note: The following procedure requires the use of hand tools and calibration
weights. If unable to perform the calibration, contact an authorized Ohaus service
organization.
1. Remove the battery cover to access the two calibration pins located in
a slot at the bottom of the scale. With the scale on under battery power,
short the calibration pins (a small slotted screwdriver may be used).
Note: When accessing the bottom of the scale, avoid placing the scale
upside down on the pan or sub-platform. Place the scale on its side.
2. “SEtUP” then the first parameter “CtY” is displayed.
3. Press -Yes successively to move through the succeeding parameters:
“dEF NO” “S1”, “S2”, “S3”, “S4”, “S5”, “S6”, “dSP”, “S8”, “S9”, “S10”,
“S11”, “S12”, “bAt”, “GEO”.
Note: Do not change the settings of these parameters. These are service
setup parameters intended for authorized servicing use only.
4. After “GEO”, “CAL NO” is displayed. Press -No to switch the setting to
“CAL YES”.
5. “CAL YES” is displayed. Press -Yes to enter calibration sequence.
