Operating the 2000 Instrument
39
Notes:
Selecting and deselecting thermocouple simulation is simply achieved by:
1)
Sending a temperature to the instrument, for example: Send the com-
mand string
“+22.89C”
to select the thermocouple simulation mode
with a simulated hot junction of
+22.89ºC
.
2)
Sending a voltage or current to the unit: for example: The command
string “
+10.0V”
will set the output level to
+10V
, which deselects
thermocouple simulation mode.
Always, the Thermocouple Simulation Set-Up data used is that previously de-
fined, thus it is not necessary to redefine these parameters for each simulation
temperature. Terminating thermocouple simulation is achieved by sending the
unit a voltage
or
current output level command, or by sending the “V” command
string without any numeric data. In this case, the output level simply stays at the
previously Calculated voltage, but terminates thermocouple simulation.
To achieve Thermocouple Simulation:
1. Press the MNU key, the display will prompt you to select either the “Stand-
by” or “Operate” state.
2. Press any arrow key repeatedly until either one of the following appears:
< Use Active CJC >
or
< Use Passive CJ >
3.
If the instrument is (presently) set to use active CJC the display will read:
“Use Passive CJ”. This feature allows you to select the opposite mode.
4.
If the displayed selection is required, then press any of the Units/Enter keys
(V, A, ºC or ºF
)
, otherwise press the CLR key to abort the selection.
To achieve Thermocouple Measurement Set-Up:
1. Press the MNU key and the display will prompt you to select either the
“Standby” or “Operate”
state.
