1. Overview
This multimeter is internal magnetic structure. It has 15
ranges, capable of metering DC voltage, AC voltage, DC
current, resistance and the capacity of dry battery under load.
It is suitable for school, factory, home and amateur of
radio enthusiast.

3. Operation way
Note:
Adjust the zero calibration device on the cap to “0” before
measuring.
If none of the ranges is working, that means the fuse in the
meter might have been damaged. Open the cap to replace
with a new fuse. Selected voltage/current range shall be
higher than the voltage/current value which you measured.
When using “OHM” range, do not measure resistance with
the circuit powered on. Discharge the capacitor before
measuring its leakage current.
Measuring DC or AC voltage:
Connect the meter across both ends of the measured
voltage and read the second scale line.
Measuring DC current:
Connect the meter and the measured circuit in series
and read the second scale line.
Measuring resistance:
Short-circuits the test bar and adjust the “OHM” zero
potentiometer until the pointer is on “0” of the first “Ω” scale
line. If the pointer cannot be adjusted to “0”, it means the
internal battery is low. Replace the battery and connect the
test bar across both ends of the resistor which to be measured.
Read the value of pointer on the first “Ω” scale line and
multiply by the factor of the range.
Measuring dry battery:
Connect the test bar across both electrode of the dry
battery which to be measured. Load current at full scale is
125mA for 1.5V range and 10mA for 9V range. If the pointer
is in the “GOOD” arc range of the third scale line, it means
the battery level is high. “BAD” arc means the battery level
is low and the arc between “GOOD” and “BAD” means the
battery level is about to be low:
Measuring dB:
Put the Range Switch to “AC10V” and read the fourth
“dB” scale line. If the measured circuit has DC component,
the test bar should be connected with a DC isolating
capacitor above 0.1UF/500V in series. When using other
“ACV” ranges to measure dB value, convert the value
according to the following table.
