Function Keys & Operation

• ON/OFF KEY:

Press the ‘ ’ switch to turn the meter on.

• W/B KEY:

Press the ‘W/B’ key to switch from BTU/(ft²*h) to W/m².

• RANGE SELECTION KEY

Press the range key to toggle between ranges, If ‘0L’ is displayed press range
to move to a higher range. If 199.9 is displayed then the reading is beyond the
instrument range.

• HOLD KEY:

Press the ‘HOLD’ key to go into hold mode. ‘HOLD’ appears on the screen to
allow you to read the data, the reading on the display is frozen. Press the key
once again to deactivate it.

• MIN/MAX KEY:

When testing in W/m² or BTU/(ft²*h) press the ‘MIN/MAX’ key to display the
max or min reading value. To turn this mode off hold down the ‘MIN/MAX’ key
for 1 second.

Operation

• Press the power key ‘ ’ to turn the meter on.

• Press the ‘W/B’ key to select W/m² or BTU/(ft²*h) measurement.

• With the sensor cap on, check that the display is zeroed. If the display in not
zeroed, adjust it to zero using the ‘Adj’ trim

• Remove the protection cap from the photo detector and expose it to the light
source in a horizontal position. Read the sunlight (irradiance) value on the
LCD display.

• Wait for values to stabilise on the display. Press ‘HOLD’ key to activate the
data hold function freezing the result on the display (NOTE: If the instrument
displays ‘OL’ the input signal is too high, a higher range must be selected).
