To set the liquid detection level, press “2nd FUNCT” key and then the “DETECT LEVEL”

key. The

µP display will show “SERVICE MODE” and “DET LEVEL”. Use the

“SCROLL” keys to increase or decrease level in which the receive signal is filtered.

Lowering the value will allow the unit to produce a reading when none existed before.

Raising the value will allow the unit to stabilize unwanted “Fault Light” occurrences as

well as helping to stabilize readings and outputs. Default level is 150. Press ‘ENTER”

key to exit function.

To adjust the 20mA output press “2nd FUNCT” key then the “20mA” key. The

µP

display will show “SERVICE MODE” and “20mA”. Use the “SCROLL” keys to increase

or decrease the 4-20mA output level. When finished with function, press “ENTER”

KEY.

To set the liquid level gain, press 2nd FUNCT” key and then the “LL GAIN “ key. The

µP display will show “SERVICE MODE” and “GAIN”. Use the “SCROLL” keys to

increase or decrease level in which the receive signal is amplified. Lowering the value

will help to stabilize unstable readings and outputs. Raising the value will allow the unit

to produce a reading when none existed before. Default level is 55. Press “ENTER”

key to exit function.

To set the Doppler’s velocity signal strength cutoff level, press “2nd FUNCT” key and

then the ‘VEL SS CUTOFF” key. The

µP display will show “SERVICE MODE” and “VEL

SS CUTOFF”. Use the “SCROLL” keys to increase or decrease level in which the

microprocessor stops reading the velocity because of low signal strength. Default level

is 100. Press “ENTER” key to exit function. Note: if velocity signal strength cutoff level

is set higher than velocity signal strength, the meter will not show flow.

To set the power fail level, press “2nd FUNCT” key and then the “POWER FAIL” key.

The

µP display will show “SERVICE MODE” and “PWR FAIL”. Use the “SCROLL” keys

to increase of decrease voltage level in which triggers a power failure warning. The

microprocessor will then store totalizer readings. The default level is 200. Press
