LE-120SA is a handheld line monitor specialized for ASYNC communication which is widely used in the industry. You can control the line monitor by soft screen touch as you do for smart phones. The light weight (300g including batteries) helps you for the field maintenance besides the system developments.

Max 999.9 seconds | Time stamp | Date time stamp: Unit selectable among "Year/Mon/Day Hr:Min," "Mon/Day Hr:Min:Sec," "Day Hr:Min:Sec.10ms," or OFF (with no record) | Line state | Records and displays the wave form and logical status of external trigger input and control line along with the transmission/reception data. | Data search | Communication error, Max 8 characters data line (Don't care and bit maskare available)), idle time more than the specified duration, time stamp within the specified time range, cueing and counting of trigger matching data |
|---|---|
| Trigger function | Up to four pairs of trigger conditions and actions can be specified. |
| Condition | Communication error, communication data string up to 8 characters (don't care and bit mask are available), idle time more than the specified duration, Timer/counter match, logical status of the control line and external trigger. |
| Action | Stops measurement/test (number of offsets until a stop can be set), validates trigger conditions, controls timer, controls counter, activates buzzer, saves monitor data into a USB flash, sends the specified character string, sends pulse output to external trigger terminal OT2 |
| Monitor conditions auto setting | Automatically configures the setting (max 460.8Kbps)*3 |
| Auto run/stop function*1 | It can automatically start and finish measurement at the specified time at the selected repeating cycle (monthly, daily, hourly). |
| Power ON auto run function*1 | It can automatically start measurement when power is turned ON. |
| Auto save function*1 | Automatically saves the monitored data in the capture memory and saves as communications log file in a USB flash memory. Restart mode and Append mode (which are ring save operation) and Max mode (in which the measurement stops at the specified capacity.) can be selected. |
