8-6 Triggering Model 2700 Multimeter/Switch System User’s Manual
Output trigger
After the device action, an output trigger occurs and is available at the rear panel Trigger
Link connector. This trigger can be used to trigger another instrument to perform an
operation (e.g., select the next channel for an external scan).
Reading hold (autosettle)
With hold enabled (HOLD annunciator on), the first processed reading becomes the
“seed” reading and operation loops back within the device action block. After the next
reading is processed, it is checked to see if it is within the selected hold window (0.01%,
0.1%, 1%, or 10%) of the “seed” reading. If the reading is within the window, operation
again loops back within the device action block. This looping continues until the specified
number (2 to 100) of consecutive readings are within the window. If one of the readings is
not within the window, the instrument acquires a new “seed” reading and the hold process
continues.
When a hold reading is acquired, an audible beep is sounded (if enabled) and the reading
is considered a “true measurement.” The reading is held on the display until an “out of
window” reading occurs to restart the hold process.
For remote operation, the hold process seeks a new “seed” once it has been satisfied and
the reading has been released. For basic front panel operation, the hold process does not
seek a new “seed” until the held condition is removed.
NOTE Hold cannot be used when scanning.
Hold example
1. Press SHIFT and then HOLD to display the present window (0.01%, 0.1%, 1%, or
10%).
2. To change the window, press the Δ or ∇ key to display the desired window.
3. Press ENTER. The present hold count is displayed (2 to 100).
4. To change the hold count, use the , , Δ, and ∇ keys to display the desired count.
5. Press DCV to measure DC voltage.
6. Apply the test signal to the input of the Model 2700. Once the signal becomes stable
enough to satisfy the hold condition, the reading is released and the beeper sounds (if
enabled).
7. Remove the hold condition by disconnecting the signal from the input. Hold will then
seek a new “seed.”
8. To disable HOLD, press SHIFT and then HOLD.
