3.4 Measuring AC or DC current
1. Turn the switch to , or for MTX 203 only
2. Toggle between AC or DC current measurement by pressing the yellow key.
3. Connect the red test lead to either A, or mA/µA terminal and black test lead to
the COM terminal.
4. Break the circuit path to be measured. Then connect the test leads across the
break and apply power.
5. Read the measured current on the display.
If current is above 10A, the DMM will sound. If current measured is above the rated current
the fuse will blow.

3.5 Measuring continuity
To avoid electrical shock and damage to the meter when measuring resistance
or continuity in a circuit, make sure the power to the circuit is turned off and all
capacitors are discharged.
1. Turn the rotary switch to
circuit to be measured.
2. Connect the red test lead to the + terminal and the black test lead to the COM
terminal
3. Detect the continuity by touching the probes to the desired point of the circuit,
if the resistance is under 50Ω, the beeper will sound, designating a short
circuit. If the resistance is above 600Ω, the meter displays OL, designating an
open circuit.
3.6 Measuring resistance
To avoid electrical shock and damage to the meter when measuring resistance or
continuity in a circuit, make sure the power to the circuit is turned off and all
capacitors are discharged.
With the continuity mode selected,
press the yellow button once to activate
the resistance measurement. Touch
with the test probes the desired point of
the circuit and read the measured
resistance on the display.
If resistance is above 60MOhm the meter
will display OL.
For MTX 202, above 40MOhm the meter
will display OL.
