Attention:Always make sure that you are using correctly set time and date values. Otherwise test results might be corrupted. Be aware that the USM 25 displays the year as a two digit number!
Operation:
– Use v to select the function TIME.
– Use the left-hand rotary knob to highlight the value that you want to change, e.g. the hour.
– Use the right-hand rotary knob to change the highlighted value.
– Use v to select the function DATE, and then use the right-hand rotary knob to select the required setting.
General configuration
Operation
• store
The current instrument setting is stored to the selected (free) data set, and the data set number (DAT-#) is automatically increased.
• datalog (only with Data Logger option)
The selected job is printed out as a report including all measured values.
• off
The Y key is deactivated. • special
as setting „hardopy“. After printout of the screen contents no form feed, every press on the Y key prints out the next hardcopy on the same page (three or four hardcopies depending on the printer).
H Note:
Please also refer to chapter 6 Documentation. Operation:
– Use v to select the function COPYMOD. – Use the right-hand rotary knob to set the required
TIME / DATE (setting the time and date)
You have to check the current date and time and, if required, set them so that these data are correctly saved together with the test results.A

Operation
– Use the left-hand rotary knob to highlight the value that you want to change, e.g. the day.
– Use the right-hand rotary knob to change the highlighted value.
HORN
In this function, you can decide whether or not an acoustic alarm should be given in addition to the visual alarm (LED A).
Operation:
– Use v to select the function HORN.
– Use the left-hand rotary knob to set the horn to on or off.
H Note:
Error alarms can be triggered unter certain circum- stances. These are caused by intermediate conditions
in instrument operation occuring when the instrumet is used, i.e. when function parameters are changed. Possible alarms occuring during instrument opera- tion (setting of functions) are to be ignored.
ANAMOD
You can output results of measurements at the analog output for external further processing. Use the function ANAMOD to configure the analog output in case there is no echo in the evaluation gate and the analog voltage has been selected for the sound path at the output. You have the following setting options:
• lo volt
The analog output supplies 0 volt. • hi volt
The analog output supplies 5 volts. General configuration

Operation
Operation:
– The function ANAMOD / EVAMOD has a double assignment (icon >). Toggle between the two functions by repeatedly pressing the corresponding key v .
– Use v to select the function ANAMOD.
– Use the right-hand rotary knob to choose the required value.
EVAMOD (echo evaluation)
This is where you can choose a method for the evalua- tion of the measured reflector echo. Depending on the instrument version used, you have various methods to choose from.
• REF (default setting)
Evaluation using the measurement of dB difference, available for all instrument versions
• DAC (only USM 25 DAC and USM 25S) Evaluation using the Distance-Amplitude Curve
General configuration • DGS (only USM 25S)
Evaluation using the DGS method Operation:
– The function ANAMOD / EVAMOD has a double assignment (icon >). Toggle between the two functions by repeatedly pressing the corresponding key v .
– Use v to select the function EVAMOD.
– Use the right-hand rotary knob to choose the required method.
