measurement mode and restores the high-level state, while the PULSE mode
outputs a configurable width of low-level pulses and restores the high-level state.

The measurement process indicator signal outputs an INDEX signal at a low level
when waiting for triggering, delay, self correction, and operation states. The
output signal is at a high level when in range configuration, data acquisition, data
transmission, and operation states. The signal can be removed from the test
object from high to low.
⚫
𝑬𝑹𝑹
The measurement of abnormal output signals can be divided into two modes:
synchronous output and asynchronous output. In synchronous output mode, the
ERR state is synchronized with the EOM output, and it is determined that the ERR
state is valid when the EOM output is low. In asynchronous output mode, the ERR
state is updated in real-time and has no synchronous timing relationship with the
EOM.

The output results of the comparator function, R-HI, R-IN, R-LO, V-HI, V-IN, V-LO
represent the comparison results of resistance and voltage, respectively. The PASS
signal is judged under different conditions based on different measurement
modes. In the resistance voltage mode, when the resistance comparison result is
R-IN and the voltage is V-IN, the PASS is at a low level; In resistance mode, when
the comparison result is R-IN, PASS is at a low level; In voltage mode, when the
comparison result is V-IN, PASS is at a low level. The UNPASS signal is a logic
inversion output of the PASS signal.

When the measurement conditions of this instrument change, I/O signals
cannot be used.

When the power is turned on, the signal and signal are initialized to HIGH
