OPERATION
3.0 GENERAL
This chapter covers Printed Circuit Board (PCB) DIP Switch Settings in
Paragraph 3.1, Output Current and Voltage to Temperature Conversion
in Paragraph 3.2, and Output to log(R) Conversion in Paragraph 3.3.
3.1 PCB DIP SWITCH SETTINGS
Before placing the unit into service, properly configure the Model 234 DIP
switch (S1). To access the PCB, use a flat blade screw driver to loosen the
top- and bottom-most screws on the front panel of a Model 234 mounted in a
Model 2308-1 or -12 enclosure, or the back panel of a Model 234D. Then
see Figure 5-3 for location of Switch S1.
If the optional CalCurve is present, set the T/R switch to T . If CalCurve is not
shipped with the unit, the factory setting is R .
If operating in temperature, enable the corresponding range number on the
PCB DIP Switch (S1). See Figure 3-1. Select only one range at a time. The
range is enabled when the switch is closed (ON). Units ship from the factory
with the DIP switch set to RANGE1 closed (0 to 10 K).
