Remove batteries when unit is not being used for a period o time.
Store instrument in protective holster when not in use.

Note
This instrument should be used by suitably trained and competent persons.

Introduction

The PVM210 is a pocket size irradiance meter with the solar detector built into the top of the meter for single handed use.With an easy to read display and a measurement hold function, the meter provides fast accurate readings of solar power for optimum positioning for the photovoltaic panel. In addition the meter can provide the solar power measurement for the calculation of short circuit current in conjunction with an ammeter, to confirm the stated short circuit current as provided by the manufacturer of the panel.

Instructions

To turn on the PVM210 press the power button The display will appear indicating the unit of measurement in watts per square metre (W/m2). If British Thermal Units (BTU (ft2h)) are required for measurement then press the UNIT button. Press the UNIT button once again to return to (W/m2) Occasionally, when first switched on, the display may show random characters or symbols. To clear the display press the ZERO button, press the ZERO button once again to return to measuring mode.

Note the solar detector is situated in the top of the meter so to perform a measurement of the solar power hold the meter with detector pointing towards the sky at a 90 degree angle to the position of the solar panel. For a more accurate measurement at the optimum angle or position, the universal camera mount on the rear of the meter may be utilised. For easy reading the measurement on the meter can be retained on the display by pressing the HOLD button Press this button once again to deactivate the hold feature. The over range indicator ‘ OL’ may appear on the display when measurements exceed 199.9 The RANGE button can then be used to extend possible readings beyond 199.9 up to 199 To switch the PVM210 off press the power button x.

Battery replacement
When the symbol is displayed, the batteries require replacement.To change batteries turn off the meter and carefully slide off thebattery cover on the rear of the meter. Remove depleted batteries and dispose of correctly. Insert a new batteries of the same type (2 x 1.5V AAA MN2400 LR03) observing the proper polarity. Carefully replace battery cover. The instrument is now ready to use.
