3.2.2 Current clamp measurement
To avoid damage to the meter and injured, Do not apply overload current when
measurement.
The meter's current ranges are 400.0A and 1000A.
To measure current (set up the Meter as shown in Figure 3-2):
1. Set the rotary switch to the DC/AC 400A or 1000A range.
2. Press the FUNC. key to select DCA or ACA measuring mode.
3. Let the wire across the binding clip which you want to measure. (Notice
the direction of current, and do not across the loop wires---Live and
Neutral both)
4. Read the displayed value.

3.2.3 Resistance measurement

To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before measuring resistance.
The Meter's resistance ranges are 400.0Ω, 4.000kΩ, 40.00kΩ, 400.0kΩ,
4.000MΩ and 40.00MΩ.
To measure resistance (set up the Meter as shown in figure 3-4):
1. Set the rotary switch to
2. Connect the black and red test leads to the COM and VΩ terminals
respectively.
3. Connect the test leads to the circuit being measured and read the
displayed value.
Some tips for measuring resistance:
• The measured value of a resistor in a circuit is often different from the
resistor's rated value. This is because the Meter's test current flows through
all possible paths between the probe tips.
• In order to ensure the best accuracy in measurement of low resistance, short
the test leads before measurement and memory the test probe resistance in
mind. This necessary to subtract for the resistance of the test leads.
