3.3.1 Selection of trigger source
You have to specify the trigger source of the trigger signal which will be received by multimeter.
Multimeter can receive single trigger through front panel and hardware trigger at Ext Trig end or
continuously take readings through auto trigger, and adopt auto trigger when the power is
connected. * (Sampling) Indicator will be lighted on in every measurement. The trigger source is
stored in volatile memory, and will be set as auto trigger (front panel) after cutting off power or
resetting remote interface.
Auto trigger:
When the trigger source is set as auto trigger, the Operation indicator in status column lights on,
and multimeter will gain continuous readings in the fastest speed allowable in the current
configuration. At this time if press down
capture and keep a stable reading on screen.
Single trigger:
When the trigger source is set as auto trigger, the Single indicator in status column will light on,
and multimeter will capture one reading or readings in specified number every time the key of
is pressed down.
External trigger:
When the trigger source is set as auto trigger, the External indicator in status column will light
on, and multimeter will receive the hardware trigger at the Ext Trig end on rear panel.
Every time there is negative pulse at Ext Trig end, multimeter will gain one reading or readings
in specified number (sampling counting).
Hint: In remote mode, multimeter can switch to local mode after pressing

3.3.2 Reading holding

It can capture and hold stable readings on the front panel display by using reading holding mode
which is quite useful when you move away probe after collecting one reading and want to hold
the reading on the screen.
Reading holding is only suitable for front panel operation, which will be neglected by multimeter
in remote operation.
There is an adjustable sensitivity range in reading holding function, which is used to determine
whether the reading is sufficiently stable and can be displayed, and is expressed by percentage
ratio of the current reading. Only if three continuous readings are all within selected sensitivity
range, can multimeter capture and display new readings.
