Volth S-11 Operating Instructions Manual - page 5
Caution
:if the measured frequency is above 30V, please press “Hz/DUTY” key at AC
electric voltage measuring range to get to the frequency function, then carry on measure
.
3.2.8 occupancy and vacancy ratio
Overload protection
: 250Vvirtual value.
3.2.9 temperature (general type)
Overload protection 250V.
3.2.10 Diode positive voltage

IV. Application method
4.1.1 RANGE key,
RANGE key for the automatic / manual measuring range key, in the trigger
movement way, before start the device it is at the automatic measuring range.
It changes to manual measuring range when press it. At manual measuring
range it goes upward one gear with one push, after it reaches the top gear, it
goes downward to the lower-gear gradually with continuous press, and it takes
turns. If press this key over 2 seconds, it changes back to the automatic
measuring range condition.
4.1.2 DH/LIGHT key
The DH/LIGHT key is maintenance / the back light control key for the reading.
A.DH reading maintenance in the trigger movement way, when touches the key
lightly, display value is locked and maintained invariably, and shows " DH "on the
monitor; When presses again, the fixed condition is relieved, enters into the usual
measure condition. B.LIGHT: back light controls press LIGHT key more than
2 seconds to open the back light control signal, opens after the back light signal
presses more than 2 seconds again switches off the back light control signal.
After opening the back light, if don’t press the LIGHT key for more than 2 seconds,
it will shut off automatically after 10 seconds
4.1.3 SELECT key The SELECT key: function choice key, in the trigger movement way.
may select the pattern: Chooses DC or AC under the DC/AC condition; Chooses
under the temperature measure condition it needs . in the DC/AC Condition

Display of similar diode positive voltage. Measuring condition
:positive DC electric
current 2mA
, reverse DC voltage approximate 3.2V.
When the transited resistance is smaller than about 50
Ω
,the buzzer beeps.
Measuring condition
:plough voltage is about 0.5V.
