5-18.Voltage Output
This interface extracts analog voltage proportional to sensor input signals. This interface is
convenient for observation and recording of waveforms with a recorder, etc., connected.
The output level is approx. 2V per 1mV/V of sensor input.
- Example of output equivalent circuit and external equipment connection
Output signals are not the indicated values themselves because they are extracted before sensor
input signals are A/D-converted.
Therefore, output signals do not synchronize with the digitally processed indicated values, such as
the digital zero and digital filter.
Output in synchronization with the indicated values requires an optional D/A converter.
Voltage output filter
Whether to extract the voltage output before or after the internal analog filter can be switched.
ON: Output after the analog filter
OFF: Output before the analog filter
How to set
5-19.
Screen Lock / Key Lock
(B5 terminal function selection)
By the setting of "B5 Function Selection," switching can be done from the WORK3 terminal
function to DSP_LOCK terminal function or KEY_LOCK terminal function.
WORK3: This can be used as the 4th work selection bit of external input.
WORK can be specified from 00 to 15.
DSP_LOCK:
When the terminal is short-circuited, key operations on the measurement
screens (comparison, hold, and graph) are disabled. However, the measurement
screen can be changed (hold to graph) and the cursor function is enabled.
KEY_LOCK: All key operations are disabled.
