These are factors to consider when measuring with Sparklike Handheld
Factors affecting the optics:
- Coloured glass
- Tinted glass (minimal effect)
- Strong background light measurement (against the sun or other source)
- Dirt on the glass (minimal effect)
- Dirt on the front optical fibre
- Mistreated front optical fibre or electrode
Factors making it easier for the spark to “jump“:
- High argon fills
- Thin glass (6mm or less)
- Thin air space (20mm or less)
- Metallic or other conductor on surface 3, such as low-e coating
- Metallic spacer bar
Factors affecting the spark:
- Thick glass (over 6 mm)
- Plastic films on glass 1 (laminated glass, coatings, etc.)
- Metallic films on glass 1
- Metallic components in glass 1
- Low Argon fill (less than 90%)
- Wide spacer (over 15mm)
- Electrode is not in contact with the glass surface
- Sparklike Handheld is not evenly pressed against the glass
- Non-metallic spacers
Correct conditions:
- Stable dark background light
- The device NOT moved during measurement
