2.35 When you use the meter to check a high-voltage
circuit, do not try to connect both test leads at once.
Instead, clip one probe to the neutral or ground lead
of the circuit (usually a bare, green, or white wire in
AC wiring circuits) using the insulated slip-on
Alligator Clips. Then probe for voltages with the other
test lead. This helps prevent you from accidentally
touching a hot wire, since you need to concentrate
on only one test lead. Failure to observe this
precaution may result in damage to the meter or

10

www.GlobalTestSupply.com

low side of a power circuit first. Never clamp onto a
hot wire first, (usually red, black, or blue in AC wiring
circuits.) If you clamp onto a hot wire first, and touch
the other probe, you could receive a shock. Failure to
observe this precaution may result in damage to the
meter or injury to the user.

2.41 To avoid damage to the meter and possible user injury,
disconnect test leads from test points before changing
the function/range. Failure to observe this precaution
may result in damage to the meter or injury to the user.

7.5 DC Current Measurement:

WARNING!

If the m agnitude of the current to be measured is unknown,

always start by setti ng the meter to the highest range, and then to

lower ranges, unt il a satisfactory readi ng is obtained.

Do not rotate the RANG E s wi tch with the input applie d to the m eter.

If the input current is higher than 10A, do not attempt to measure!

Use caution when measuring current in a circuit wi th vol tages

above 50 VDC. Do not use m eter to measure current in circuit s

whose voltage exceeds 250V AC/DC.

7.5.1 Connect the black test lead to the COM jack. Connect the
red test lead to the 10A jack unless it is known that the
input current is less than 200mA. If the current is les s
than 200mA, connect the red test lead to the uA mA jack.

7.5.2 If the red test lead is inserted into the 10A jack, set
the RANGE switch to the 10 A position.
