3.3 Setting Measurement Time
Measurement time can be set in all measurement functions except of Diode, Frequency, Temperature and
Square waveform output. Measurement time is displayed on secondary display in the format of “0.00.00”. The
maximum measurement time is 9h.59m.59s.
Follow below steps to set up measurement time:
1) Select a suitable measurement range.
2) Press
TIMER
key to enter the measurement time setup mode. The secondary display displays “0.00.00”
3) Press
SELECT
key and the last digit of “0.00.00” on the secondary display glitters, which means this digit
can be adjusted. Use the
◄▲▼►
keys to adjust measurement time.
4) Press
TIMER
key to validate the new setup, and the measurement time is started to calculate immediately.
5) Press
TIMER
key again to display calculating time on secondary display.
6) When it reaches the measurement time, an indication given by continuous beepers reminds that time is up.
When calculating time is displayed, press
SELECT
key to switch display of measurement time and calculating
time on secondary display. Measurement time can be adjusted at any point. After measurement time is
adjusted, press
TIMER
key to validate the new setup. If new enter measurement time is less than calculated
time, indication will be given by continuous beepers immediately.
To stop the beepers, please press
HOLD
key when calculating time is displayed.
When the timer is activated, the preset measurement time and calculating time are not changed when
measurement functions and operations are changed. Press
HOLD
key when calculating time is displayed, the
timing function will be stopped and calculating time will be removed. To remove the preset measurement time,
press POWER switch to restart the meter.
3.4 Analog Bar Graph
The function of analog bar graph is imitating the analog needle of the meter but without the overshoot. The bar
graph refreshes data 40 times per second. Because the graph responds 10 times faster than the digital display,
it is widely used in the application of peak value test and zero calibration. It is also commonly used in observing
the rapid variation of input signals.
The bar graph has 21 segments. The number of lit segments is relative to the full-scale value of the selected
range. One unit of the bar graph represents 4000 counts/bar except when in the relative mode. The polarity is
indicated at the left of the bar graph (Positive polarity “+” is not displayed).
3.5 Square Waveform Output
The square waveform output is a very useful function. With adjustable square wave frequency and duty cycle,
users can carry out the pulse wave modulation (PWM) output, and adjust the voltage control, timer control and
clock syntherization.
