Output mode only displays the signal screen but allows the
operator to cycle between the TC setting and the mV setting.
The position of the cursor is indicated by the flashing cursor
under the selected digit.
This method is much more efficient then the ‘press and wait’
method and allows the operator to instantly change the
magnitude of the output.
The flashing cursor indicates which digit can be changed by pressing the up or down arrows to
increase or decrease the value. The digit will change with each key press. Each digit value
cycles from 0 to 9 or 9 to 0 when the arrow keys are continually pressed.
The operator can change the position of the cursor with the
discrete right or left arrow key presses. The cursor will continually
shift from LSD to MSD or MSD to LSD if the arrow keys are
continually pressed.
This scheme allows the operator to change the output values
quickly without having to wait for fixed or dual speed value
changes and the need to time the key release. The output signal
changes and settles to the selected value as soon as the Enter
key is pressed. The displayed process value is recalculated with
the new output values and displayed.
1.7.1 Using Output Mode
The PROBE BUDDY is used in output mode to test and verify that the monitoring or control
instruments are working or to simulate changes in the sensor signals using the ramp mode for
either or both signals. To modify the process, it is generally more useful to ramp only the mV
signal and set the temperature output to the typical operational level.
To set up for output mode:
•
Change PROBE BUDDY to output mode by pressing the IN/OUT key until the signal
direction icon points left (out).
•
Using the correct TC cable, connect the TC leads to the instrument thermocouple
inputs. Observe the polarity of this connection. The negative lead of thermocouples is
typically the red wire. NOTE: B type TC connections can be made with standard copper
wire.
•
Connect the mV cable to the instrument millivolt inputs. Observe the polarity of this
connection.
•
Move the digit cursor to the TC display by pressing the TC/mV key if it is not already
flashing under the TC value.
•
Press the ◄ or ► keys to
move the cursor, and
use ▲ or ▼ keys to change
digit value.
