In the beginning
It is of our great pleasure to purchase Riken portable combination gas detector model
RX-516/RX-517 this time. This instrument is an explosion-proof type portable gas
detector which is designed to measure the presence of the following gas at crude oil
tankers shown below.
RX-516
•Hydro carbon(HC) :0-100.0%LEL/2-100.0vol% (Iso-butane cal.)
•Oxygen(O2) :0-25.0 vol%
•Hydrogen sulfide(H2S) :0-100.0ppm
RX-517
•Hydro carbon(HC) :0-100.0%LEL/2-100.0vol% (Iso-butane cal.)
•Oxygen(O2) :0-25.0 vol%
•Hydrogen sulfide(H2S) :0-100.0ppm/0-1000ppm
This instruction manual is a guide book for operation to use and operate model
RX-516/RX-517. It is kindly requested to read and understand this content by
experienced users as well as beginners. The following headline shall be shown to carry
out the safety and effective work in this instruction manual.

１．Caution in operation
To maintain the function for safety, follow the following instruction.
Warning
・Do not modify nor change the circuit and structure etc. When modify or change, it could
not maintain the function.
・This is explosion‑proof product. Battery has to be replaced in non‑hazardous zone. The
battery replacement in hazardous zone shall be out of the scope for explosion‑proof
product.
・This is explosion proof. Be sure to operate with carrying case on.
・Do not measure in the environment of oxidant gas presence. When measure, it may shorten
the sensor life.
・When measure under organic solvent gas presence, do it in short time and make sensor
cleaning by sucking fresh air after measurement.
Caution
・Do not drop or damage it. This is a fire instrument. When strong shock is given, the
function may be the case not to maintain. Especially, when power is on, the shock from
outside is easy to receive. So, the caution at this point is needed.
・Keep it from the direct splash of water. As this is not of drip‑proof, it may cause
the trouble by splash of water.
・Do not give the electric noise such as by walkie‑talkie during operation. When receive
the electric noise, it may cause the trouble of reading and instrument.
・When the atmospheric pressure and temperature are changed, it may affect the gas reading.
・When it is condensed, the normal operation is impossible.
・Be sure to mount the internal filter and filter tube.

３．Operation
３−１．Check item before operation
RX‑516 or 517 instrument：
・Check that there is no damage for display unit etc.

・Check the dirt of inside cotton filter. When it gets dirt, replace the cotton filter with
new one.
・When water drops remain, wipe it out and change it with new one.
・Check that these is no crack or damage.
・Check that these is no loose mount on the nipple.
Gas sampling hose：
・Check that there is no crack, creek or twist on the instrument.
３−２．Preparation
（1） Dry batteries are put into instrument.
（2） Put carrying case on to instrument.
（3） Connect the ①instrument(Gas inlet)＋②Filter tube with flow monitor＋③Sampling hose
respectively.
For gas sampling, 3 kinds tip formation are available and change it according to he measuring
environment.
Standard: Sampling hose (1m) and gas sampling probe
Optional: Sampling hose (30m) with plummet
Sampling hose with floating gas sampling head (30m)
・Connection with sampling hose
Take knurling part by fingers and pull ①arrow mark to → direction. Put it to the arrow
mark ②←direction. Then, release the finger from the knurling part. Further press and
sound tick, and then, locked.
