• Comparator Output Specifications
Output signal
HIGH, IN, LOW, and BUSY
Operation
When D/A > upper limit: HIGH = 1
When upper limit ≥ D/A ≥ lower limit: IN = 1
When D/A < lower limit: LOW = 1
When converting signal: BUSY = 1
LED (on display) corresponding to HIGH, IN, and LOW lights
Signal level
TTL level
• External Trigger Specifications
Input level
TTL level
Operation
If a high level signal is applied externally when measurement is held, measurement trigger is
activated on the falling edge.
When a trigger occurs, the LED on the front panel section lights.
