Display Symbols; Audible Feedback - Wavetek Meterman HD160B Manuel D'utilisation

Dangerous voltage warning (also double beep tone). Indicates input voltages
higher than 30VAC or 60VDC.
Polarity indication
Low-battery voltage

Audible Feedback

The meter emits a single beep when a parameter is changed, a "valid" front panel
button is pushed, or Auto Min Max or Probe Hold values are updated. A double
beep indicates a dangerous input voltage (>30VAC or 60VDC).
The meter emits a continuous tone in the case of input overload, for continuity
measurement when resistance is <50Ω, and for current measurements, when the
10A input is used and the current exceeds 10A.
Analog Bargraph
The analog bargraph indicates which percentage of the range a displayed
measurement relates to. The zero segment is lit when the instrument is turned on.
If the input is less than 40% of range, each segment equals 1% of range. If the
input is above 40% of range, each segment equals 10% of range. Example: a
300mV input in the 1V range (30%) is represented by 30 segments
0 10 20 30
( ); a 600mV input (60%) will be represented by 6 segments
( 0 ).
Exception: in the 40mA range, one segment represents one mA.
The Safety Tester™ is designed to provide a quick sure look at a circuit for
voltages up to 480VDC or ACrms. It will indicate the five voltage levels even if
the meter has a dead battery or blown fuses. ¶ Position the Range Selector
Switch in the Safety Tester™ position. Â Connect the test leads to the COM and
VΩ inputs then across the circuit to be tested. ' Note which, if any, LED(s) is(are)
lit for voltage level.
WARNING - The Safety Tester™ is designed as additional level of fail-safe
protection, but should not be trusted on a meter which has known operational
problems or has been damaged. It can not indicate the presence of voltage over
