15. Stop watch
This function allows you to measure elapsed times up to one hour.
ê
Run the function selector switch (6) to “V - - - ”
ê
Use the pushbutton “AUTO/MAN” (4) to select a measuring range between 3 V
and 1000 V.
ê
The function stop watch cannot be activated in the range 300 mV - - -.
14. Event counter
Event counter is only possible with a voltage measurement in(DC+AC) mode.
With this function it is possible to measure and indicate the number of elapsed
time of the events and the total of the function activation. Voltage signals are
indicated with an amplitude of >2 500 digits, with a maximum, repetition rate of
0.25 Hz (minimum, duration of 4 seconds) and a minimum, event time of 2
seconds.
w
by pressing the yellow multi- function pushbutton (5) longer, this
is Confirmed
w
by the buzzer sounding twice, by switching the meter off.
Note:
The correction value for the lead resistance remains stored when exiting the
function and when switching off the multimeter.
To determine the lead resistance, only use the multimeter you use to measure the
temperatures. Only this way, it is assured that the measuring error is within the
specified range.
ê
Set the function switch (6) to V - - -.
ê
Switch the signal on as for voltage measurement.
For other functions see the following table.
With this function the meter is not switched off automatically.
It is possible to return directly from event counter to voltage measurement
w
by pressing the yellow multi- function pushbutton (5) longer. This is confirmed
by the buzzer sounding twice. The voltage measuring range which was set the
last time, keeps switched on.
w
by actuating the function switch (6).
ê
Set the function selector switch (6) to V
ê
Connections are made the same way as for voltage measurement. See foot
note 6) on page 22.
ê
Briefly press the yellow multi-function pushbutton (5).
The meter switches to frequency measurement. The frequency is displayed
on the LCD.
See Section “17. Specifications” for the lowest measurable frequencies and
the maximum permissible voltages.
ê
From frequency measurement, you can directly switch back to voltage
measurement
w
by pressing the yellow multi-function pushbutton (5) for a long time. The meter
acknowledges this with the buzzer sounding twice. The voltage measuring
range last selected is maintained.
w
by operating the function selector switch (6).
13. Temperature measurement
With Pt 100 and Pt 1000 temperature sensors you can measure temperatures on
0
0
the range from-200 (-100) C ...+850 C
0
ê
Set the function switch (6) to “ C ”.
ê
Connect the sensor to the two sockets for which access is allowed.
The meter automatically detects the connected sensor( Pt 100 or Pt 1000)
0
and shows the measured temperature in C on the digital display.
Notes:
This measurement automatically considers the lead resistance of the Company
temperature sensors which are available as accessory.
Temperature measurement
considering sensor lead resistances up to 50
W
Lead resistance of sensors having a value differing from that of Company sensors
can be considered up to a value of 50
W
as follows:
ê
Briefly press the yellow multi-function pushbutton (5).
The temperature measurement range is now selected which considers a
changed lead resistance of the sensor. This is indicated on the LCD by the
“ZERO” symbol.
ê
Briefly press the yellow multi- function pushbutton (5) again.
The LCD now displays the resistance value which the meter automatically
considers. So that you can recognize that is the resistance correction value
0
on the temperature measuring range, the “ C” character is simultaneously
shown.
ê
You can set the line resistance correction value as follows:
Press the DATA-MIN/MAX pushbutton (3) to increment the value, or the
AUTO/MAN pushbutton (4) to decrement the value. Each time the
pushbutton is briefly pressed, the value changes by one digit. You pass
through fast, when you press the pushbutton longer.
ê
Briefly press the yellow multi- function pushbutton (5) again.
The LCD displays the measured temperature in consideration of the changed
lead resistance. The symbol “ZERO” (18) in the LCD shows you this.
ê
Each following time the yellow multi- function pushbutton (5) is briefly
pressed, the display changes between measured temperature with changed
lead resistance and correction value of the lead resistance. You can exit the
function “temperature measurement with changed lead resistance”
