visibility. You can slew through a wide range of the adjustment to optimize the
display.
3.2 Using the Keypad
The most commonly used keys on the keypad (Gain, Freeze, Save, Enter, and Slewing
Keys) are close to your left thumb.
The keypad is grouped and color-coded according to function. The outlined section of
yellow keys on the left side of the keypad is used primarily for calibrating. The separate
group of grey keys on top are the function keys, designed to provide easy access to preset
parameter values. The EPOCH 4PLUS also has extensive data storage features controlled
by the datalogger keys at the right side of the keypad.
3.2.1 Enter Key
While you can access most functions directly via the instrument keypad, you can change
all essential ultrasonic controls by using of the
[ENTER] key and one of the four green
slewing keys [], [], [], and []. This method provides control of virtually all
instrument settings with the thumb of the left hand. Multiple presses of [ENTER] will
toggle through each of the instrument parameters. The parameter highlights when
activated. Use the [], [], [], or [] key to change an activated parameter value.
Press the [ENTER] key multiple times to toggle through the instrument settings. To move
quickly through the sequence, press [ENTER] multiple times in succession or simply
hold down the key to reach the desired function.
3.2.2 Direct Access Operation
Most commonly used parameters also have their own individual keys to provide direct
access to the parameter setting. To use the EPOCH 4PLUS in this manner, press the
appropriate key to change the parameter and then either press one of the function keys
(F1-F5) to select preset values, or adjust the value using the [], [], [], and []
slewing keys. For example to change the gain, press [GAIN]. Press [F1], [F2], [F3], [F4],
or [F5] to select one of the preset dB steps or use the slewing keys for fine adjustments.
In some cases the parameter appears as a second function above another key. To change
these parameters, press [2nd F] and then the appropriate key to access that parameter.
Whenever a function is opened in the full screen display, the EPOCH 4PLUS provides
prompts in the Abbreviated Status window directly above the A-Scan display on the left
side.
3.3 Summarizing Keypad Functions
The EPOCH 4PLUS has two keypads. The top keypad, located directly underneath the
display, is made up of five function keys: [F1], [F2], [F3], [F4], and [F5].
