GENERAL

a. Overview
Ensure the Oxymitter 5000 is at normal op-
eration. The diagnostic LEDs will display the
operating cycle. All other LEDs should be
off (Figure 3-5).
1. DIAGNOSTIC ALARM LEDS. If there
is an error in the system, one of these
LEDs will flash various blink codes
(Section 5, TROUBLESHOOTING). In
the case of multiple errors, only one
will be displayed based on a priority
system. Correct the problem and cycle
power. The operating display will return
or the next error will be displayed. The
alarms are:

6 will allow you to monitor with a mul-
timeter: the heater thermocouple, O
cell millivolt, and the process O
(a) TP1 and TP2 monitor the oxygen
cell millivolt output which equates
to the percentage of oxygen pres-
ent.
(b) TP3 and TP4 monitor the heater
thermocouple.
(c) TP5 and TP6 monitor the process
gas or the calibration gas pa-
rameter. The maximum reading
available from these test points is
30 VDC. This corresponds to 30%
oxygen concentrations.
