Appendix 57
10.7 Clearing Locked-Up Scale (888888 Error)
Several configuration errors can result in the scale locking up with a display that shows all 888888 s. These errors
include the following:
• If no force balance is connected to the DC-190, SPEC 8, bit 3, must be set to 0 (0xxx).
• If a force balance is attached, SPEC 8, bit 3 must be set to 1 (1xxx) and SPEC 9, bit 2 (force balance
type), must be set to 1 (x1xx, Ohaus Explorer).
• If no printer is attached to the DC-190, SPEC 10, bit 3, must be set to 0 (0xxx).
• SPEC 16 and SPEC 17 must assign a different location for each scale, whether it is present or not. These
bits must be configured to show scale assignments for
Internal Scale 1 , Internal Scale 2 , External Scale ,
and Force Balance . See example below.
The following configuration for SPECs 16 and 17 contains duplicate entries for both Internal Scale 1
and External Scale.
Do NOT set SPECs 16 and 17 to a configuration such as that shown below: a
lockup condition will result if this configuration is selected.
Should the DC-190 become locked up in all 888888 s as a result of invalid specification settings, an authorized
service technician can perform the following procedure:
1. Unplug scale from AC outlet.
2. Press and hold the 3 and 9 keys while plugging AC cord into outlet.
3. The display shows S-on . Release the 3 and 9 keys.
4. Press and hold REZERO key while keying access code 141 (display will show SPC00 ). Use the + key to
advance to the incorrect SPEC and edit its value.
5. When done, press the * key to store the new values, then press the MODE key to return to weighing
mode.
