1. INTRODUCTION
Thank you for purchasing a Skye Instruments External 1 to 4-channel Amplifier. This product may have
between 1 and 4 current output light sensors connected to it. This amplifier's function is to transform the current
from one of Skye Instruments' unamplified sensors into a voltage output, scaled over a desired range pre-
determined at the time of ordering (e.g. 0 – 2V, 0 – 5V, etc.).
Alternatively, just one or two sensors may be connected and scaled to different ranges on different
channels, so that two potential ranges of light can be accurately measured (e.g. this may be useful when the
maximum light levels are unknown, at the outset).
Our range of amplified sensors have the amplification is built into the sensor housing, which is the
ideal situation. This is a product for those situations where this is not appropriate (for example, where there is
a limitation on sensor height). The cable between an unamplified sensor and an amplifier should be as short
as possible and fixed down firmly.
Please Note:
REMOVE THE LID SLOWLY AND GENTLY AS THERE IS A WIRE ATTACHED TO IT THAT SERVES AS THE
SCREENING CONNECTION FOR THE LID.
PLEASE ALSO ENSURE THAT ON REPLACING THE LID THAT THE WIRE DOES NOT GET TRAPPED IN
THE SEALING LIP.
