This section details the programming for the analog input.
TEMPERATURE INPUT TYPE
250 uA 2 U 1k RES tc-r r392
2.5 mA 10 U 10k RES tc-S r672
25 mA 25 U tc-t tc-b r427
250 mA 100 U tc-E tc-n
2 A 200 U tc-J tc-C
250 mU 100 RESs tc-k r385
Shaded selections indicate the available temperature input types. Select the
desired input type.
TEMPERATURE SCALE
°F °C
Select the temperature scale. If changed, those parameters that
relate to the temperature scale should be checked.
ICE POINT COMPENSATION
For TC Input Range Selection only.
ON OFF
This parameter turns the internal ice point compensation on or off.
Normally, the ice point compensation is on. If using external
compensation, set this parameter to off. In this case, use copper leads
from the external compensation point to the meter.
INPUT UPDATE RATE (/SEC)
5 10 20
Select the ADC conversion rate (conversions per second). The
selection does not affect the display update rate, however it does
affect alarm and analog output response time. The default factory
setting of 20 is recommended for most applications. Selecting a fast
update rate may cause the display to appear very unstable.
DECIMAL RESOLUTION (Display Units)
0 to 0.0 (temp)
0 to 0.000 (curr/volt/ohm)
Select desired display resolution. The available selections are
dependent on the Input Type selected (
tYPE
) .
ROUNDING INCREMENT
1 2 5
10 20 50 100
Rounding selections other than one, cause the Input Display to
‘round’ to the nearest rounding increment selected (ie. rounding of
‘5’ causes 122 to round to 120 and 123 to round to 125). Rounding
starts at the least significant digit of the Input Display. Remaining
parameter entries (scaling point values, setpoint values, etc.) are not automatically
adjusted to this display rounding selection.
DISPLAY OFFSET
-1999 to 9999
The display can be corrected with an offset value. This can be used
to compensate for probe errors, errors due to variances in probe
placement or adjusting the readout to a reference thermometer.
DIGITAL FILTERING
0.0 to 25.0 seconds
The input filter setting is a time constant expressed in tenths of a
second. The filter settles to 99% of the final display value within
approximately 3 time constants. This is an Adaptive Digital Filter
which is designed to steady the Input Display reading. A value of ‘0’
disables filtering.
