Page 4: Product Overview
It can be used to measure any closed pipe, straight or crooked with a constant diameter. The Well Watch 660DL consists of a control unit and a probe which are connected by a latching hinge. The control unit contains the driver electronics, processor, display, and keypad, while the probe contains a speaker, a microphone and a threaded spout to connect to the test pipe. - Page 5 Several accessories are available for the Well Watch 610/660 which can be found on our website at www.enoscientific.com.

Page 20: Logging
Factory default values. LOGGING The Well Watch 660DL includes a built-in data logger which can record the measurement data automatically at preset intervals when automatic logging is enabled. Each data point includes the system time and date, well ID, depth, temperature, battery voltage, signal strength, and error codes. -
Page 21: Usb Communications
If the log period is set to zero minutes, then every reading is logged. USB COMMUNICATIONS The Well Watch 660DL contains an expanded memory which provides enough memory to record one data point per minute for over 50 years. This memory supports a windows compatible file system which can be accessed using the USB port. -
Page 22: Rs232 Communications
The TX terminal on the well watch goes to pin 2 on the D connector, RX goes to pin 3 and GND goes to pin 5. A simple serial to USB adapter is available from Eno Scientific or most computer stores to use with laptops without serial ports. The default serial configuration on the Well Watch is 19200 baud, 8 data bits, 1 stop bit, no parity, and no flow control. - Page 23 <ret> set baud rate (CAUTION – once the command is accepted, communications will cease until the terminal setting is changed to match) 0 –300 1 – 1200 2 – 2400 3 – 4800 Eno Scientific Well Watch 660DL Page 23...

In this case, the Well Watch will track the descending water level until it gets to the perforations and then stick at the start of the exposed perforations as the water level continues to descend.

Page 35: Additional Notes
The maximum range is limited by the maximum time during which the echo is monitored, and the strength of the echo signal. Uncased wells drilled through porous material can attenuate the signal faster than the rated distance, making detection impossible. Eno Scientific Well Watch 660DL Page 35... -
