Select the desired input range.
TEMPERATURE SCALE
For TC and RTD Input Range Selection only.
°F °C
Select the temperature scale. This selection applies for Input, MAX, MIN,
and TOT displays. 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 40 80 160
Select the ADC conversion rate (conversions per second). Temperature inputs
can not be set higher than 20 updates per second. The selection does not affect
the display update rate, however it does affect setpoint and analog output
response time. The default factory setting of 5 is recommended for most
applications. Selecting a fast update rate may cause the display to appear very
unstable.
DECIMAL RESOLUTION (Display Units)
0 to 0.0000 (curr/volt)
0 to 0.0 (temp)
Select desired display resolution. The available selections are dependent on
the Input Range selected (
rANgE
) .
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
-199999 to 999999
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. This value is automatically
updated after a Zero Display to show how far the display is offset. A value of
zero will remove the affects of offset.
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.
FILTER BAND
0 to 250 display units
The digital filter will adapt to variations in the input signal. When the
variation exceeds the input filter band value, the digital filter disengages. When
the variation becomes less than the band value, the filter engages again. This
allows for a stable readout, but permits the display to settle rapidly after a large
process change. The value of the band is in display units, independent of the
Display Decimal Point position. A band setting of ‘0’ keeps the digital filter
permanently engaged.
When the meter is programmed for TC or RTD, the following programming
steps are not active.
