TOS6200A/6210 Basic Operation 4-13
Measurement of an offset value
1.
Connect the lead wires whose resistance components are to be mea-
sured to the OUTPUT terminals.
2.
Short-circuit the ends of the leads connected to the LOW and HIGH ter-
minals of the OUTPUT terminals.
3.
Press the SHIFT + MAIN/OFFSET keys (press the MAIN key while
holding down the SHIFT key) to invoke the offset measurement screen
(OFFSET).
In the OFFSET screen, the test current, test frequency, and timer indicate the
values shown before switching screens.
4.
If necessary, set test current, test frequency, and timer values.
5.
When "READY" (ready status) is displayed in the OFFSET screen,
press the START switch. This begins offset measurement.
When you press the STOP switch or when the time set in the timer elapses, the tes-
ter stores the offset value of that time in memory. When offset measurement ends,
the tester reverts to ready status.
Press the MAIN key to display the MAIN screen. Check that the offset function is
ON, then begin the test.
To check the offset value, display the OFFSET screen by pressing the MAIN/OFF-
SET key again while holding down the SHIFT key.
To adjust OFFSET
A measured OFFSET value can be finely adjusted using either the SHIFT and
F2 (ADJ+) keys or the SHIFT and F3 (ADJ-) keys together.
“OVER VOLT” blinks on the LCD.
A value obtained by multiplying the test current value by the upper reference
value has exceeded 5.4 V. Test cannot begin under the current conditions.
Change the setting referring to “OVER VOLT” in 4.9.1, "Setting Output out of
the Operation Range.”
“OVER VA” blinks on the LCD.
The setting has exceeded the maximum rated output. Test cannot begin under
the current conditions. Change the setting referring to “OVER VA” in 4.9.1,
"Setting Output out of the Operation Range.”
