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.

f.Remove voltmeter leads.

g.Remove jumper wire.

3-3 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:

	G02	G04
United States	1M03192G01	1M02982G01
United Kingdom	1M03192G02	1M02982G02
Germany	1M03192G03	1M02982G03
France	1M03192G04	1M02982G04
Italy	1M03192G05	1M02982G05

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.
