Kikusui TOS5050A - VOLTAGE readout (digital voltmeter)

4-14 TOS5051A/5050A
[20] AC/DC test mode message
This message indicates whether the AC or DC test mode has been selected with the
TEST VOLTAGE switch. The selectable modes are AC or DC.
• The TOS5050A only has the AC test mode. It has no DC test mode message.
• When you change the modes with the TEST VOLTAGE switch, the message
blinks to indicate that the modes have been changed. Blinking stops when you
press the STOP switch or when you start the test by pressing the START switch.
• During the TEST-ON period (period that “TEST” is lit), the TEST VOLTAGE
switch is disabled. During this period, it is possible that the actual position of the
switch does not conform with the TEST VOLTAGE RANGE message or the AC/
DC test mode message.
• Do not let the TEST VOLTAGE switch get caught between two range positions. If
you turn ON the POWER switch while the TEST VOLTAGE switch is caught in
the middle, the test voltage range message shows a blinking “0 kV” to notify that
the setting has not been confirmed (in addition, if the TOS5051A is in the middle
of switching between AC and DC, both “AC” and “DC” light up simultaneously).
The “READY” message will disappear to show that the tester is not in the
READY status. If this happens, turn the TEST VOLTAGE switch accurately to a
range position. When you do so, the tester will enter the READY status
(“READY” is lit). In this status, blinking stops when you press the STOP switch
or when you start the test by pressing the START switch.
[21] VOLTAGE readout (digital voltmeter)
The VOLTAGE display (digital voltmeter) indicates the output voltage with a 3-
digit 7-segment readout. It constantly monitors the output terminal voltage.
On the TOS5051A, the digital voltmeter acts either as an AC voltmeter or a DC
voltmeters according to the AC or DC mode selected by the TEST VOLTAGE
switch.
1. Measuring ranges and resolutions
2. Display formats
• Due to the measuring resolution, the readout may not be “0.00 kV” when the out-
put terminal voltage is zero volts.
