Encoder Inputs

The optional Olympus B-scan encoder BSCAN-ENC (U8779522) can be connected to
the EPOCH 650 Digital Out connector using the CBAS-10669-0010 (Q7790008)
encoder cable. This setup provides single axis quadrature encoder inputs exclusively
to the B-can feature embedded in the Corrosion Module (see "Corrosion Module" on
page 275). Other encoders instead of the BSCAN-ENC can be supported using
customized cables.

Analog Output

The EPOCH 650 ultrasonic flaw detector offers an optional programmable analog
output. This analog output allows the instrument to continuously output thickness or
amplitude information to an external device, such as a strip chart recorder or a
computer outfitted with an analog/digital converter card.
The information is output as a scaled voltage, on either a 0–1 V or 0–10 V scale. The
EPOCH 650 is connected to the external device by means of the analog output
LEMO 00 connector on the top of the instrument. Each scaled voltage is output at full
PRF rate up to 2 kHz.
To access the analog output setup parameters
1. Choose Meas Setup > A-Out (group 3/5) to display the A-Out setup page (see
Figure 8-1 on page 141).
2. Press NEXT to move through the form fields.
3. Use the adjustment knob or keypad to select an available parameter setting:
• Reading
Used to select the measurement type (thickness or amplitude) to output.
Available settings are:
— Gate1 Thickness
— Gate2 Thickness
— Gate1 Current Amplitude
— Gate2 Current Amplitude.
• Output
Used to select the range of voltage output from the unit. Available settings
are:
