Disabling autozero to increase speed
Disabling autozero (setting it to OFF) can increase measurement speed. If autozero is disabled,
accuracy will drift with time and temperature.
Turning autozero OFF will disable the autozero function and possibly increase measurement speed.
To minimize drift, setting autozero to ONCE will perform an autozero operation one time (at the time
when it is selected), and then disable the autozero function. For a more detailed discussion of
autozero, see the
(on page 2-37) topic.
To configure autozero from the virtual front panel:
1. Press the
CONFIG
key, and then select
MEAS
from the menu.
2. Select
AUTO-ZERO
, and then press the
ENTER
key or the navigation wheel .
3. Select the mode (
OFF
,
ONCE
, or
AUTO
), and then press the
ENTER
key or the navigation
wheel .
4. Press the
EXIT (LOCAL)
key as necessary to return to the normal display.
Refer to
(on page 2-38) for details about configuring autozero from a
remote interface.
How do I upgrade the firmware?
For information on upgrading the firmware, see
(on page A-2).
How do I use the digital I/O port?
You can use the 2606B digital input/output with the trigger model or to control an external digital
circuit, such as a device handler used to perform binning operations. To control or configure any of
the six digital input/output lines, send commands to the 2606B over a remote interface.
To use the 2606B digital I/O in a trigger link system (TLINK), connect it using a 2606B-TLINK Trigger
Link Cable and configure the 2606B digital input and output lines.
For more information about the 2606B digital I/O port, see
(on page 3-78).
How do I make contact check measurements?
For information about making contact check measurements, see
(on page 4-15).
How can I change the line frequency or voltage?
The 2606B requires a line voltage of 100 V AC to 240 V AC (±10%), and a line frequency of 50 Hz or
60 Hz. The factory configures the 2606B to automatically detect and operate at the appropriate power
line frequency each time the instrument power is turned on. In noisy environments, it may be
necessary to manually configure the instrument to match the actual line frequency. For more
information, see
(on page 2-8).
