Reset
R
Reset channel after reading
Valid for
C
,
HSC
,
ST
and
CV
channel types,
which are reset to 0 after returning their
current value.
Also valid for digital output channel types
(DSO, DNO, DBO) which invert the state of
each bit after returning its value.
Internal Shunt
(DT80/
81 Series
1 only)
NSHUNT
Disconnect internal 100R shunt
between # terminal and AGND
Allows # terminal to be used for shared-input
voltage measurements
Delay
PT
Force precise timing
Valid for
DELAY
,
DSO
,
WARN
and
RELAY
channel types. Forces a precise (+/- 1ms)
delay time even for long delays.

Data
Manipulation
DF
Difference
Δx
Returns the difference (xUnits) between the
latest reading and the previous reading
DT
Time difference
Δt
Time difference (seconds) between the latest
reading and the previous reading
RC
Rate of change
Δx / Δt
Rate of change (xUnits per second) based on
latest and previous readings and their
respective times
RS
Reading / time difference
x / Δt
Rate of change (xUnits per second). Useful
when the sensor reading is already a
difference (e.g. resetting counters)
IB
"Integrate"
( x – Δx / 2 ) Δt
"Integration" with respect to time (xUnits .
seconds) between the latest and the previous
readings (area under curve)
Digital
Manipulation
TRR
Time from rising edge to rising
edge
Normally used for digital channels.
If used on analog channels then channel
factor is interpreted as a threshold value.
TRF
Time from rising edge to falling
edge
TFR
Time from falling edge to rising
edge
TFF
Time from falling edge to falling
edge
TOR
Time of rising edge
TOF
Time of falling edge
Reference
Channel
TR
Use this channel's value as
thermocouple reference junction
temperature
Any non-thermocouple temperature sensor
measuring isothermal block temperature.If
already compensated use 11SV(TR) as
reference channel (11SV always returns 0.0).
TR channel temperature is used for all
subsequent thermocouple measurements in
this schedule
TZ
Use this channel's value to
correct the DT80's electrical
zero
This zero would be measured at the
isothermal block. TZ channel zero is used for
all subsequent thermocouple measurements
in this schedule
BR
Use this channel's value as
bridge excitation voltage
BR channel voltage used for all subsequent
BGV
measurements in this schedule
