Front panel operation
Automatically setting long integration time (“AUTO TIME” sub-menu)
Press ENTER when “LINT AUTOTIME #1, #2”, “ACQUIRE TIMES” appears on the
display. If the correct trigger level is selected in the previous step and the DUT is operating, the
Model 2306 will automatically determine the INTEGRATION times. If the trigger level is
incorrect or the DUT is not functioning properly, the message “LONG INT TRIG NOT
DETECTED” will be displayed.
(See the LONG INT TRIG NOT DETECTED note on
page 20
.)
Long integration display mode
Long integration measurements are displayed with the long integration display mode
selected. This display mode is selected as follows:
NOTE
To display measured readings if the instrument is in the settings mode, press the SET
key until the blinking stops (the measured readings can then be displayed). To
determine if the instrument is in the settings mode, check for a blinking cursor in a
digit of the voltage or current field (if present, the instrument is in the setting mode).
1. Press the DISPLAY key to access the display menu.
2. If the desired active display is not selected, use the LEFT and RIGHT keys to toggle the
active display. The top line of the display will show which output channel is active.
3. Press the UP or DOWN key until “LONG INTEGRATION” is displayed and press
ENTER.
4. To stop taking long integration readings, press any front panel key. As long as the
instrument remains in the long integration display state, the measurement process can be
resumed by pressing the UP or DOWN key.
NOTE
LONG INT TRIG NOT DETECTED message
This message may take a few seconds to appear. With the trigger edge set to
NEITHER, this message may appear if level setting causes no rising edge detection.
A valid trigger level is not required if the trigger edge is set to NEITHER. For the
battery channel (#1), this message will only appear if the range of the trigger level
setting matches the selected trigger level range. For the charger channel #2, the
trigger level range setting is not user selectable.
NOTE
If you select AUTO TIME to set the integration time, the pulse timeout message
“LONG INT TRIG NOT DETECTED” will display if the output is OFF. This
message indicates that the integration time has not been updated. To update the
integration time, select AUTO TIME after the output is turned ON.
