5.6 Test Voltage Display Inaccurate
The KATC-V display of secondary test voltage can be changed by adjusting
R9 on Card 2
[See Figure 3, above]
.
1. Place an accurate voltmeter across terminals S and C on the KATC-V

6.2 Serial (RS-232C) Output Port
If the RS-232C port option was purchased, the DB-25 connector on the rear
of the KATC-V can be connected to a computer with a serial port. Pressing
the HOLD/PRINT button initiates a printout. A sample printout is shown be-
low:
{CR}{LF}{CR}{LF}
VT TEST: {CR}{LF}
TEST RATIO PHASE ACCURACY {CR}{LF}
VOLTAGE ERROR ERROR CLASS {CR}{LF}
(VOLTS) (%) (MINUTES) (%) {CR}{LF}
120.0 +0.002 +0.26 0.01 {CR}{LF}
{CR}{LF}{CR}{LF}
where
{CR}{LF}
indicates a Carriage Return, Line Feed sequence.
This printout will vary depending on the position of the front panel switches.
The KATC-V communicates at 1200 baud, 8 data bits, no parity, and one
stop bit.
