6.2 Signal Descriptions
80
PRINT The current measurement value prints when the PRINT signal
transitions from High to Low.
IN0, IN1 When not using the TRIG and PRINT functions, they can be monitored
as general-purpose input terminals with the :IO:IN? command.
❖ 8.6.2 Device-Specific Commands; (6) External I/O (Page 139)
CAL When manual self-calibration is selected with FAST or MEDIUM
sampling rate, self-calibration begins when the
CAL signal transitions
from High to Low.
Self-calibration requires about 55 ms to complete.
When the SLOW1 or SLOW2 sampling rate is selected, the
CAL signal
is ignored.
❖ 5.8 Self-Calibration (Page 66)
Output Signals ________________________________________________
ERR Indicates a measurement fault.
The Synchronous ERR output setting causes ERR output to be
synchronous with EOC output, while with the Asynchronous ERR
output setting causes ERR output to follow actual (asynchronous)
contact of the probes with the test object.

❖ Measurement Fault Output Signal (ERR) Setting (Page 82)
INDEX The INDEX signal is output during the Trigger Wait, Delay, Self-
Calibration and Calculation states.
This signal is not output while measuring the resistance of test objects.
This signal transitions from Off to On to indicate that the test object
can be removed.
EOC This signal indicates the end of a measurement (End-Of-Conversion).
Hi, IN, Lo These are the results of comparator decision.
BIN0 to BIN9,
OB (Out of BINs)
This output indicates the BIN No. that was judged to be IN by the BIN
measurement function.
If the decision does not apply to any BIN, the OB signal is output.
When BCD outputs are selected, the BIN signals are not available.
❖ BIN No. Output/BCD Signal Selection (Page 82)
OUT0 to OUT7 The output signals are controlled by the :IO:OUT command.
❖ 8.6.2 Device-Specific Commands; (6) External I/O (Page 139)
BCD1-0 to
BCD6-3
These are BCD outputs. BCD1 is the lower digit, and BCD6 the upper
digit.
BCDx-0 is the LSB, and BCDx-3 is the MSB.
When BIN outputs are selected, the BCD signals are not available.
Minus signs are not output. Also, temperature measurements are not
output as BCD.
❖ BIN No. Output/BCD Signal Selection (Page 82)
INT.GND ,
INT.VCC
These are outputs of the instrument's internal 5 VDC and GND.
