Measuring NCV (Non-Contact Voltage)
See Figure
-8-
1.
Range switch may be set to
OFF
or any function/range.
2.
Test leads are not used for the
NCV
test.
3.
Press the
NCV
button. The display goes blank, a tone sounds and the red LED
next to the
NCV
button on the front panel lights up to verify that the instrument
is operational. While pressing the button hold the top-center of the meter
(sensor location) close to the conductor/circuit in question.
4.
If a voltage of in the range of 70 to 600 V ac is present, a tone sounds and the
red LED next to the NCV button on the front panel lights up.
Testing Battery Voltage (1.5 and 9 volt)
See Figure
-9-
1.
Set the Range Switch to the appropriate
BATT
setting,
1.5V
or
9V
.
2.
Connect the Test Leads: Red to
BATT 1.5V
or
BATT 9V
, Black to
COM
3.
Connect the Test Probes across the battery. The meter applies an appropriate
load to the battery.
4.
Read the display. A good 1.5 volt battery should measure >1.2 V, and a good 9
volt battery should measure > 7.2 V.
Additional Features
Input Lead Warning
The 30XR emits a continuous tone to indicate that the user has placed the unit in a
potentially dangerous configuration. Specifically, a test lead is in a current
connector and the Range Switch is set to measure some other function. If, in this
configuration, the DMM is connected to a voltage source, very high and potentially
dangerous current could result. The meter includes fast acting fuses as additional
protection for all current ranges.
MIN MAX Measurements
XW
WARNING
To avoid erronoeus readings, do not change the position of the
Function/Range Switch while the MIN MAX function is enabled.
The MIN MAX function works within the active measurement mode to capture and
display the minimum or maximum reading associated with that measurement.
Pressing the
MIN MAX
button for less than 1 second enables the function and
shows
MIN
or
MAX
along with the appropriate minimum or maximum reading on
the display. Each subsequent press toggles between the two modes. To exit the
function, press the
MIN MAX
button for more than 1 second.
HOLD Measurements
XW
WARNING
To avoid erronoeus readings, do not change the position of the
Function/Range Switch while the HOLD function is enabled.
The
HOLD
function is used to make a measurement and hold the reading after
removing the leads from the test circuit. Pressing the
HOLD
button during a
measurement will capture and hold the reading. Pressing the
HOLD
button again
will release the display for subsequent measurements.
