displaying in terms of distance, the screen can be set to be viewed either in units per
division (for example 1.000in/div or 25.00mm/div) or units full scale (for example,
10.00” full scale or 250 mm full scale). Units full scale describes the distance over the
entire screen range.
When displaying in terms of time, all distance parameters (range, zero offset, gate
position, material thickness, minimum depth, and all soundpath data) are displayed using
microseconds (µs) instead of inches or millimeters.
To change the units of measure, follow these steps:
1. Move the highlight bar over Unit and press [ENTER].
2. Use the slewing keys to select the desired unit setting and press [ENTER].
3. Press [OPTION] to exit.
3.7.3 Analog Out
The EPOCH 4PLUS is capable of continuously outputting the depth or amplitude
information to an external device, such as a strip-chart recorder or a PC outfitted with an
analog/digital converter card. The information is outputted as a voltage, either on a 0-1
volt or 0-10 volt scale.
Select the output scale and then connect the EPOCH 4PLUS to the external device via the
analog output LEMO connector on the top of the instrument.
To change the voltage output scale, follow these steps:
1. Move the highlight bar over Analog Out and press [ENTER].
2. Use the slewing keys to select the desired voltage scale setting and press [ENTER].
3. Press [OPTION] to exit.
3.7.4 Clock
The EPOCH 4PLUS has a real time internal clock. The clock can be set once, and the
instrument then stamps individual files in the datalogger with the correct time/date
whenever information is saved to that file. The time/date is also updated whenever
additional information is saved to the file. The clock is reset during an instrument Master
Reset and when it initially ships from the factory.
To set the clock, follow these steps:
1. Move the highlight bar over Clock and press [ENTER].
2. Use the slewing keys and the datalogging keys to enter the correct date mode, date,
and time.
3. Press [F1] to set or [F2] to cancel the updated settings.
