Reset type/level (after or during recharge)
CTR = Charge Tracking Reset
If the gauge is connected to the battery during recharge,
the gauge will track the battery charge level.
For standard “B” profile, CTR Full = 2.35 vpc and
CTR Empty = 2.10 vpc.
OCR = Open Circuit Reset
If the gauge is disconnected from the battery during
recharge, the gauge will retain the last indication. It will
advance to full when reconnected only if the battery voltage
is above the OCR level. For standard (“B”) reset, OCR =
2.09 VPC*.
*VPC = volts per cell.

Display
The Curtis Model 803 combines in one instrument a
completely solid state LED battery state-of-charge
indicator, an LCD hour meter, and lift lockout.
Only when battery is properly charged is right
most LED lit. As battery’s state-of-charge decreases,
successive LEDs
light up, one at
a time.
Here, the LED flashes
indicating “energy
reserve” (70% discharged).
The left most 2 LEDs flash
indicating “empty” (80%
depth of discharge). At this
point, lift lockout occurs.
