PRINCIPLE OF HOW THEY WORK-DISPLAYS-RESULTS
This family if Test instruments operate through a keypad interface. The
number of keys and their function are different on each model. All
interactions between the user and the instrument is done via the keypad.
The testers have a liquid Crystal Display and two or three terminals.
Each push button or key has a function.
DIGITAL DISPLAY
The digital Liquid Crystal Display is large. It measures (W)98mm x (H)24mm
and has a 2Lines of 16 Characters.
Language can be changed on demand.
Dutch / French / German etc... (factory fitted at order)
FUSED
The tester is fused by a fast blow 500mA fuse.
CROWBAR PROTECTION
In case of misuse, a crowbar is integrated and will blow the fuse.
This crowbar will reduce the damages in case of user mistake.
The crowbar is activated at less than 6V (ac or dc).
AUTOMATIC BATTERY TEST
When the tester starts, it test it's batteries by drawing a heavy current from
the batteries. During that heavy current, it measures the battery voltage and
display it for a few seconds on the display.
During normal use, the tester monitor the battery voltage, but without
drawing a battery test current. It just measure the battery while in normal use.
SAFETY VOLTMETER
Once the battery test is terminated, the tester goes automatically into the
Voltmeter mode.
It has an Automatic voltmeter AC and DC.
The safety voltmeter even has a Hold function built-in.
The Hold Function will automatically put the last valid reading on hold if the
user disconnect the leads.
This is a safety feature, where the user does not need to observe the display
but instead observe where he has his hands and probes. This way, safety is
increased.
The Safety Voltmeter works up to Vdc 900V (both polarities) with resolution
of 1V and 1% accuracy. It also measure up to Vac 700V, with the same
resolutions and accuracies.
