NOTE
The voltage given above is for an am-
bient (machinery space) temperature
of 77°F (25°C). For each degree of am-
bient temperature above or below 77°F
(25°C), add or subtract 0.242 mV from
the nominal. Example; at 87°F (31°C),
the nominal voltage of -322.3 should
be increased (made less negative) by
10 x 0.242 or 2.42 mV, making the ad-
justed nominal -319.9.

MODEL 218A ELECTRONICS SETUP
Before beginning operation, it is important that
the probe heater set point of the existing elec-
tronics be changed to support the World Class
3000 probe. To convert the Model 218A Digital
Electronics Package for use with the World
Class 3000 Probe and Heater Power Supply,
an EPROM change is necessary. Remove Main
PCB and check back of board to identify unit as
G02 or G04. The replacement EPROM needed
is as identified below:

NOTE
The replacement EPROM when using a

multiprobe averager unit is
1M02982G10.
To replace the EPROM, proceed as follows:
a. Shut off and lock out power to the electron-
ics package.
b. Open electronics enclosure.
c. On the Main PCB, Figure 3-2, locate and
remove old EPROM.
d. Replace with new EPROM.
e. Close electronics enclosure and power up
system.
