· It is best to begin by selecting the highest possible range (10A)
when the order of magnitude of the current to be measured is
unknown.
· Do not connect the multimeter in series with the circuit to be
measured until the last possible moment. Then switch on the circuit
to be measured.
· If the range chosen is too high, first switch off the circuit to be
measured, then change the setting of the rotary switch, and switch
on the circuit again.
· Do not under any circumstances change the range or disconnect
the test leads while measuring: this may give rise to switching
current spikes and overvoltages which can damage the multimeter
or blow the fuses unnecessarily.
· To minimise overheating and to prevent thermal drift, measure-
ments in the high current ranges (5A and 10A) should be limited to
a few tens of seconds.

· The DATA HOLD key operates the memory mode for all conven-
tional multimeter functions (voltmeter, ammeter, ohmmeter).
· Pressing the key once freezes the value displayed
· Pressing the key a second time clears the display and allows a
new measurement to be carried out.
