Velocity Of Detonation Measuring Instrument
Guide & Manual
DESIGNED & MANUFACTURED BY
Swiss Manufacturer of Detonating Velocity Measuring
Instruments for Explosives and Propellants Since 1936
2 | P a g e
MEASURING METHOD AND PRINCIPLE OF
OPERATION
The Explomet 2™ has 5 independent timers measuring the time
intervals between the illumination of 6 fiber optic cables.
It is not necessary to respect an order to connect the optical fibers either
on the explosive or the Explomet 2.
The instrument can record from 1 to 5 V.O.D measurements at a time
depending on the number of optical fibers used from 2 to 6.
The Explomet 2 operates in one of the following modes:
1: Velocity and Time: the first optic fiber to be illuminated gives the
starting signal: start and the last fiber to be illuminated gives the stop
signal: stop. The Explomet 2 measures the time intervals in micro
seconds between the illumination of two consecutive optic fibers and
calculates the Velocity of Detonation (V.O.D) in meter per second [m/s].
2: Time Only: The optic fibers are illuminated randomly. The Explomet
2 measures the time intervals (in microseconds) between the
illumination of the first and the second fiber, then between the second
and the third fiber, and so on until a maximum of 6 optical fibers.

OPERATING INSTRUCTIONS
BATTERY CHARGING
Before the first use of the Explomet 2, charge the batteries using one of the following charging options:
1) Car charger cable
2) Charger Ansmann AC48
Charging time is about 4 hours.
OPTICAL FIBER PREPARATION
Follow the instruction on the attached BROADCOM / AVAGO document to prepare the cable
terminations and connectors
Avago HFBR Characteristics & Guide: Download Available at the Bottom of Plastic
Optic Fiber & Connectors Page on our Website
To check the proper transmission of light through the optical cable from the test area to the Explomet 2
you can simulate a measure with the supplied Ledlenser flashlight.
We recommend protecting the last meters of the optical fiber plugged into the explosive with a
3 [mm] diameter P.V.C. pipe. This insure a better immunity against parasitic light at explosion’s
time and will also reduce the amount of optical fiber destroyed at each measure.
We also recommend the use of our:
Reinforced Duplex POF 1-2.2mm Characteristics: Download Available at the Top of
Plastic Optic Fiber & Connectors Page on our Website
Reinforced 6 Channels POF 1-2.2mm Characteristics: Download Available at the Top of
Plastic Optic Fiber & Connectors Page on our Website
For the preparation of the optic fiber:
o Cut the needed length of fiber optic
o Fix an optical connector at one end, see description on:
Avago HFBR Characteristics & Guide: Download Available at the Bottom of Plastic
Optic Fiber & Connectors Page on our Website
o With your Swiss knife, cut straight the other end of the optical fiber
o connect the necessary optical fibers (from 2 to 6) to the Explomet 2. Either directly or through
one of the following reusable optical cables:
1. DUPLEX CABLE (2 channels = 1 V.O.D measurement)
2. SURFACE CABLE (6 channels = 5 V.O.D measurements)
o It is not necessary to respect an order to connect the optical fibers either on the explosive or
the Explomet 2.
10 | P a g e
OPTICAL FIBER INSTALLATION
Important to know before you start:
o The quality and accuracy of your results depends in part on how your optical fibers are
prepared and installed on the explosive or propellant.
o Ensure that the length of your optical fibers is more or less equal. Too big a difference
in length (for example: 30 [m]) can contribute to distorting your V.O.D measurement.
o It is not necessary to respect an order to connect the optical fibers either on the
explosive or the Explomet 2.
o For Dynamites, Water gels Explosives or Cartridges Explosives, respect a minimum
distance of three times the diameter of the cartridge between the primer and the 1st
optic fiber.
o We recommend protecting the unused optical receivers of the Explomet 2 with the
supplied grey plastic caps avoid any stray light.

Example
V.O.D measurement of an emulsion explosive cartridge (50[mm] diameter, 1000[mm] length) on a test
area.
1. Position your explosive cartridge flat on the ground on the test area.
2. Choose at which end you will insert your primer. For example, on the left.
3. Measure the diameter of the cartridge using your folding meter and multiply by 3. For example,
the diameter of your explosive is 50 [mm], multiplied by 3 that makes 150 [mm].
4. From the left end of your explosive, measure ~150 [mm]. This will mark the point where you
insert your 1st optical fiber.
5. To do this, with your white marker, draw a mark at ~150 [mm] on the explosive.
6. Use the punch of your Swiss Army Knife to drill a small 2[mm] hole at the place of your mark to
insert the optical fiber into your explosive. Insert the fiber about 10 to 20 [mm] perpendicular to
the explosive.
11 | P a g e
7. For added security, attach the optical fiber to the explosive using your tape.
8. Choose a segment with a minimum length of 50 [mm] from the 1st fiber and mark the distance
again with your red marker. This gives you where to insert your 2nd optical fiber.
9. Measure the distance between fiber 1 and 2. For example: 225 [mm]. You will need to report
this distance on the Explomet 2 when entering the data in mode 1. Velocity and time.
10. If necessary, insert other optical fibers and proceed in the same way as before (points 8 and 9).
11. Connect the necessary optical fibers (from 2 to 6) to the Explomet 2. Either directly or through
one of the following reusable optical cables:
• DUPLEX CABLE (2 channels = 1 V.O.D measurement)
• SURFACE CABLE (6 channels = 5 V.O.D measurements)
12. It is not necessary to respect an order to connect the optical fibers either on the explosive or
the Explomet 2.

BATTERY CHARGER
Use only the Ansmann AC48 or car charger cable and its adapter supplied with the Explomet 2 to
ensure the proper operation of your device.
CALIBRATION
The Explomet 2 is calibrated only once during its manufacture and this for the duration of its use which
is on average of fifteen years. Nevertheless, we remain at your disposal for any verification of your
device and can issue a certificate of V.O.D/Calibration to guarantee the perfect functioning of your
measuring instrument.
GENERAL
As the Explomet 2 uses microelectronic technology, do not expose it to humidity, dust and preserve it
from shocks. Be sure to close the optical receptors with the supplied grey plastic caps.
