BIT 1: A one (1) will appear if the Series 801 fails the inter-
nal oscillator test. The remote probe electronics may
be defective. Consult factory.
BIT 2: A one (1) will appear if the Series 801 fails the open
probe test. Ensure proper connection of the white
wire between terminal block TB1 and the probe
screw terminal in the probe housing. Consult factory
if unsuccessful.
BIT 3: A one (1) will appear in this position if the Series 801
fails the shorted probe test. Remove the white wire
from the probe screw and measure resistance
between probe screw and ground.
BIT 4: A one (1) will appear in this position if the signal
between the probe electronics and transmitter is out
of range. A direct “short” across the probe will also
trigger Bit 4. Ensure proper connection and polarity
of wiring between probe housing and transmitter.

An eight digit code will be displayed by pressing ENT at the
Extended Errors prompt. By reading this code from right to
left, information on both probe circuits can be obtained. The
first four bits (starting at the right) are associated with probe
circuit 1, and the second set of four bits is associated with
probe circuit 2, as shown below.
