5.1 Solar power meter Operating Instructions
• Press the power key '
Э
' to turn on the meter.

• Press the 'W/B' key to select W/m
or BTU(ft
• Remove the protection cap of the photo detector and expose it to the light source in
horizontal position. Read the sunlight value on the LCD display.
• Wait for values to the stable on the display. Press 'HOLD' key to activate the data hold
function blocking the result on the display
(NOTE:If the instrument display 'OL'. the input signal is too strong.
A higher rang must be selected.)
• When the measurement completed, fit the photo detector cap and check that the
indication value should be '000' regargless of the range. If no, adjust the '0ADJ'
trimmer on '000' before pressing the power key to turn off the meter.
5.2 Digital Multimeter Operating Instructions
AC/DC Voltage Measurements
• Insert the black test lead into the negative COM terminal and the red test lead into the
positive V terminal.
• Set the function switch to VAC or VDC position.
• Connect the test leads in parallel to the circuit under test.
• Read the voltage measurement on the LCD display.
Caution: Do not measure AC/DC voltages if a motor on the circuit is being switched ON or
OFF. Large voltage surges may occur that can damage the meter.
AC/DC Current Measurements
• Set the function switch to the μA/mA position.
• Insert the black test lead into the negative COM terminal and the red test lead into the
positive μA/mA terminal.
• For current measurements up to 2000μA DC/AC, set the function switch to the mA
position
• Press the MODE button to indicate "DC"/"AC" on the display.
• Remove power from the circuit under test, then open up the circuit at the point where
you wish to measure current.

• Touch the black test probe tip to the negative side of the circuit.
• Touch the red test probe tip to the positive side of the circuit.
• Apply power to the circuit.
• Read the current in the display.
Resistance Measurement
• Set the function switch to the Ω position.
• Insert the black test lead into the negative COM terminal and the red test lead into the
positive Ω terminal.
•Touch the test probe tips across the circuit or part under test. It is best to disconnect
one side of the part under test so the rest of the
• circuit will not interfere with the resistance reading.
• Read the resistance in the display
Warning: To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any resistance measurements. Remove the batteries and unplug
the line cords.
Continuity Check
• Set the function switch to the
position.
• Insert the black test lead into the negative COM terminal and the red test lead into the
positive Ω terminal.
• Press the MODE button to indicate on the display
• Touch the test probe tips to the circuit or wire you wish to check.
• If the resistance is less than approximately 100Ω, the audible signal will sound. If the
circuit is open, the display will indicate "OL".
Warning: To avoid electric shock, never measure continuity on circuits or wires that have
voltage on them.
Diode Test
• Set the function switch to the
position.
• Press the MODE button to Touch the test probes to the diode indicate on the display.
under test. Forward voltage will typically indicate 0.400 to 0.700V. Reverse voltage will
indicate "OL". Shorted
• devices will indicate near 0V and an open device will indicate "OL" in both polarities.
