Operating the 2000 Instrument 31
•
To deselect the multiplier:
1. For example:if the display is:
+10.00000mV
2. Press the
m
key to change the display to:
+.0100000 V
•
To use the selected multiplier:
1. For example: if the display is:
+10.00uV
2. Press the
m
key to reformat the display to:
+0.01000mV
—And—
1. For example: if the display is:
+.1000000 V
2. Press the
µ
key to reformat the display to:
+100000. µV
Direct Entry of Temperature Data
The temperature of the hot junction of the thermocouple system to be
simulated may be directly entered similarly to entering output voltage or
current. The difference is that the display format is fixed. And although the
multiplier may be used numerically during the entry, the display format is
unaffected.
For example: If
120mºC
is entered, then a temperature of
0.12ºC
will
be selected. The display format used for temperature simulations also
includes information regarding the thermocouple type.
Examples of the format used are:
+1000.00°C R
and
+1000.00°F R
In both cases, the selected thermocouple type is “R”
.
For details on the
method used to select the thermocouple type, cold junction compensation
technique and cold junction temperature, refer to
Thermocouple Simulation
or Measurement Set-Up paragraph.
Reversing Polarity of the Present Output Level
As previously mentioned, the polarity of the present output level (or
simulated temperature) may be reversed by simply pressing the
+/- key.
