5 SETTING OF FUNCTIONS
5-18.
Voltage Output
This interface extracts analog voltage proportional to voltage・current input signals. This interface
is convenient for observation and recording of waveforms with a recorder, etc., connected.
The output level is approx. 0.6V per 1V at voltage input and approx. 0.3V per 1mA at current input.
Output signals are not the indicated values themselves because they are extracted before voltage・
current input signals are A/D-converted.
Chapter
Therefore, output signals do not synchronize with the digitally processed indicated values, such as
5
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

Screen Lock / Key Lock
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.
