Delmhorst Instrument C-2000 - Manual (Page 6)

A hard Reset is required if, after changing the battery, the
display is frozen. This is sometimes caused by the interrup-
tion of contact between the battery and the battery lead wire.
Resolve this as follows:
Disconnect the battery. Press and hold the Read key for 15
seconds. Press and hold the Check key for 15 seconds.
Release the Check key. Connect a fresh battery to the lead
wire in a single action, making sure to align the poles
properly and without interrupting contact. If the display
remains frozen, repeat the procedure. If this procedure
does not solve the problem, refer to the Service for Your
Meter section.
