6. When the desired temperature scale appears, press ENTER. The conditioner
will now tell you whether its internal reference-junction compensation is cur-
rently enabled. If it is, you may now disable it, if you intend to provide your
own Controlled Ambient Temperature Zone for reference-junction purposes.
(Note that if an external cold junction is being used, you must supply the
Model 3510 with an already 32°-compensated TC signal on copper wire.)
If the internal cold-junction compensation is in effect, the conditioner will dis-
play "CLD J":
If it is NOT presently in effect, "NO CJ" will be displayed:
7. To toggle between "CLD J" and "NO CJ," press the top or bottom segment of
any digit display (even if it is blank).
8. When the desired state appears, press ENTER to return to the "TYPE" display.
Then press SETUP to return to the "Setup" display, and proceed to Section
3.a.6.
3.a.5.b SETTING THE MODEL 3530’S LVDT INPUT RANGE
The Model 3530 LVDT Conditioner must be set to match the full-scale input
range of the displacement transducer.
1. After pressing the RANGE button, press ENTER. The number "5," "10," or
"20" will now appear, depending on the current input range setting. The fol-
lowing table shows how each number corresponds both to a "normal" input
range and to a "long-stroke" input range (for "normal" vs. "long-stroke" cabling,
see Section 2.a.3):
Range "Normal" "Long-Stroke"
Number Input Range (f.s.) Input Range (f.s.)
5 0 - 150 mV/V 0 - 1 V/V
10 0 - 300 mV/V 0 - 2 V/V
20 0 - 600 mV/V 0 - 4 V/V
2. To change the input range, you can cycle forwards or backwards through the
allowed settings by pressing the top or bottom segment, respectively, of any
digit display (even if it is blank).
3. When the desired range number appears, press ENTER to return to the
"RANGE" display. Then press SETUP to return to the "Setup" display, and pro-
ceed to Section 3.a.6.
