Operation Manual for ProScale LCD Readouts, version 4
Page 4 of 16
Power:
These readouts are powered by a single CR123 lithium battery. Unless
specially ordered, the readout will deliver to you with the battery installed.
New for this version readout:
A battery indicator will appear on the left side of the LCD screen.
There are 3 tiers of battery shown, which represent the voltage
level of the battery. When only one tier is left, a new battery
should be prepared for installation soon. Typical battery life for
these readouts is 18 months, but life will depend on how often
the readout is being used, and which programming options are
enabled.
Battery Replacement:
Remove the 2 screws in the upper right and lower left corners of the readout.
Lift the cover off. Remove the old battery and install a new battery, noting the
proper orientation. Replace the cover and screws.
External Power:
These readouts also support use of external power if:
1. The scale type is any model
except
Model 150B or Model 250B type.
(Consult factory for assistance if scale type is not known.)
2. The input power is 12
– 24 volts DC. (AC power source is not
supported.)
3. The 3-position terminal strip for the readout has been supplied.
4. Common for the machine a
nd the readout must be the same. A “hot
chassis” condition may permanently damage some or all of the
electronics.
New for this version readout:
If external power is used, but a power loss occurs, the readout will
automatically switch to battery power (if a battery is installed). Likewise, the
readout will automatically switch to external power is restored.
