Note 1: Above values are the results of commuting
ability in the phase measurements of the
converter.

determination repeatability
* The density (consistency) determination resolution
stated above is defined due to manufacturing
limitation to make reagents with stable distribution
and a minimum difference of fluid density
(consistency).
<Notice>
1. Install a sample tap near the LQ500 as close
as possible to get an accurate density
(consistency) measurement using the LQ500.
2. Take several samples in rapid sequence for
more accurate density (consistency)
measurement with less human error factors.

*1 A rubber heater is installed at the RF part of the
detector.
Need to prepare an additional power supply either
100Vac type or 200Vac type for it by yourself.
Determine one of them at the specification code.
This option is available for detector only.

*1 10m (32.8 ft) length is packed as standard.
*2 Need to prepare this cable by the customer.
*3 Need to use a sheathed cable.
*4 If the diameter of the cable is smaller than the inside
diameter of the packing, enlarge the cable diameter to
the same size as the packing by wrapping around the
cable.
This dimension is coming from a diameter of the
cable gland of the LQ500.
