the KATC-V display next to the display of test voltage.
Each time the HOLD/PRINT button is pressed, the voltage at which
the displayed results were taken is recalled to the display for a short
time. The display then returns to showing the presently applied volt-
age.

Record the data. If you have the RS-232C option, the data is
automatically sent to the output device upon pressing HOLD/PRINT
a second time.

4.3 One-to-One Test
The One-to-One Test is a method for checking the calibration of the
KATC-V and associated standard transformer.
1.
If you are using the KATC-V without one of the Knopp Transformer
Testing Systems, connect the standard transformer as shown in Fig-
ure 2 (earlier in this manual). When using the KATC-V with the KVTS
or 1G2, refer to the instruction manual for your system for One-to-
One test instructions.
2.
When power is first applied to the KATC-V, the display will momen-
tarily show
RESET
. After this message disappears, test voltage data
is displayed.
3.
Slowly
adjust the test voltage to the desired value.
Note that the
data will not be displayed until the Test Voltage reaches 40
VAC!!!
U
CAUTION
IF THE TEST VOLTAGE IS APPLIED TOO QUICKLY, THE
KATC-V ALARM MAY BE FALSELY TRIGGERED. ALTHOUGH
THE KATC-V HAS CIRCUITRY TO MINIMIZE THE EFFECTS OF
EXCESSIVE ERROR VOLTAGE, THE PROTECTION IS NOT
TOTAL. IF A GENUINE ERROR CONDITION EXISTS (WRONG
POLARITY OR WRONG RATIO), APPLYING VOLTAGE TOO
QUICKLY WILL INCREASE THE CHANCES OF DAMAGE TO THE
KATC-V AND TO ASSOCIATED EQUIPMENT.

After the data is displayed (RATIO ERROR, PHASE ERROR, and
