1. Introduction
1.1 Receiving and Inspection at time of delivery:
1. Check the packing list to account for all items received.
2. Inspect the shipping container for damage. Record any visible damage or shortages
on the delivery record.
3. File a claim with the carrier.
4. Notify your ROOTS® Prover supplier immediately.
Do not accept any shipment with evidence of mishandling without making an immediate inspection for
damage prior to signing the carrier’s delivery record. Do not attempt repairs or adjustments, as doing
so may be a basis for voiding all claims for warranty or insurance claim with carrier.
1.2 General Information
The Model 5 ROOTS Prover is an integrated computer controlled system designed for shop or field
proving of rotary and diaphragm-type positive displacement gas meters (80M for shop use only). The
Prover is designed for transfer proving utilizing air only as the test medium, and electric blowers mounted
on a manifold or a skid provide the test air flow (vacuum).
The Prover system consists of the following major components: Master Meter(s) as the measurement
reference standard; pressure and temperature Transducers; Blower(s); flexible hose(s); electronic cables
and accessories with a storage case; a Flow Rate Controller for automatic flow rate adjustment and test
sequencing; and computer software for calculations and presentation of the flow test data. The Prover also
has the unique capability to test ROOTS meters equipped with the Integral Micro Corrector (IMC/W2).
A personal computer (not included) is required to run the software.
The software program stores predetermined Field Meter test configurations. It performs all calculations
at the end of each test run and displays the pressure and temperature differentials, Field Meter proof,
Field Meter accuracy, and percent error. Test reports may be saved to diskette, the PC hard drive, and/or
may be printed. You can configure the software for Imperial or Metric display and storage of data.
The Model 5 10M, 2M/10M ROOTS Prover and Mobile 5M ROOTS Prover are portable units. They may be
transported into the field for on-site testing. The Prover is a precision instrument - operate and maintain
it in accordance with factory recommendations as outlined in this manual to ensure accurate and repeatable
results. Transport it with care and ensure that it is properly secured and covered for protection from moisture
and dirt.
The blowers are not explosion proof. Do not operate them when testing in a hazardous area.
Do not operate the Prover in the presence of explosive or flammable gasses or an explosion may result.
The Prover system is not designed for intrinsic safety.

1.5 Theory of Operation
The Prover operates as a transfer test. The meter under test (Field Meter) registers volume and compares
it to the volume registered by a Master Meter. Blowers are used to pull a vacuum, which draws ambient
air into the Field Meter and through a connecting hose directly into the Master Meter.
In the normal test set-up, the mass of air passes through the meter under test and then through the Master
Meter. Since the Master Meter’s characteristics are known, the meter under test can be characterized based
on the difference in its performance parameters as compared to the Master Meter. This difference in
performance is expressed in terms of accuracy (proof and percent error are also displayed).
1.6 Precautions
• No copies of this disk or any of the information contained there on shall be used
for any purpose other than to operate the Model 5 ROOTS Prover.
• Do not operate the Model 5 ROOTS Prover in the presence of flammable gas or
an explosion may result.
• Do not operate the Model 5 ROOTS Prover in the rain or while standing in water
in order to avoid a potential electrical shock.
• Check upstream and downstream blocking or bypass valves to ensure that they operate
properly and are leak tight in the closed position before powering any device.

6ROOTS®Model 5 Prover Software Manual
• CAUTION: Purge all Field Meters (Conventional Meter Proving) of gas prior to testing.
At NO time should power be applied when the Prover is in a possibly explosive atmosphere.
Observe all company safety rules, regulations, and procedures.
• If the ROOTS Model 5 Prover is equipped with both the 2M and 10M or the 5M and 20M
Master Meters, make certain that the unused Master Meter has the inlet quick-disconnect
nipple capped or plugged to prevent any possibility of overspeeding the unused Master Meter.
• (10M/80M ROOTS Model 5 Prover only) Never connect the 10M Master Meter directly
to the female quick-disconnect coupling of the 10M Blower Manifold when the 80M Master
Meter is being used.
• The majority of commercial computers/laptops are designed for an office environment.
Refer to your computer's reference manual for specific operating information and
specifications. Refer to the Care/Proper Handling of Diskettes or CDs in the Help Directory.
• When entering Drive Rate and Test Volume during the configuration of a Meter Test, you must
enter proper values. If the correct Drive Rate is selected from the screen, only valid Test
Volumes are displayed. If "Other" is selected in either the drive rate/pulses/test, or the
test volume selections, it is up to you to enter the proper values.
• (All Provers except 10M & 2M/10M). If “Restart” is pressed during a test, the Prover may restart
the main blower with the main valve partially open. If this occurs, a sudden surge of air may
apply undue stress to both the Master and Field Meters. Press “Stop” first. Stop the test and
allow the main valve to close fully before pressing “Restart.”
• When testing ROOTS intermittently integrated Temperature Compensated (TC) Meters, make
certain to double the standard Pulses/Test value. This is due to the requirement of the special
routines for testing ROOTS Meters to count transitions instead of pulses. One up and one
down transition equal one pulse.
• Controlled software should only be used with the 20M.
