INTRODUCTION
1.1 UNPACKING
Remove the Packing List and verify that all equipment has been received. If there are any
questions about the shipment, use the phone number for the Customer Service Department
nearest you.
Upon receipt of shipment, inspect the container and equipment for any signs of damage. Take
particular note of any evidence of rough handling in transit. Immediately report any damage to
the shipping agent.
The carrier will not honor any claims unless all shipping material is saved for their
examination. After examining and removing contents, save packing material and carton
in the event reshipment is necessary.
Verify that you receive the following items in the shipping box:
QTY DESCRIPTION
1 Low-Cost Ratemeter/Totalizer/Controller with all applicable connectors attached.
1 Owner's Manual
1 Set of Mounting Brackets
If you order a configured meter with options, you will receive the meter with option
boards installed. Refer to Table 2 1 for more information on options.

1INTRODUCTION
1.2 SAFETY CONSIDERATIONS
This device is marked with the international ca tion symbol. It is important to read this
manual before installing or commissioning this device as it contains important information
relating to Safety and EMC (Electromagnetic Compatibility).
Unpacking & Inspection
Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate
the unit if damage is found.
This instrument is a panel mo nt device protected in accordance with EN 61010-1 (safety
requirement standard of electrical equipment for measurement, control and laboratory).
Installation of this instrument should be done by Qualified personnel. In order to ensure safe
operation, the following instructions should be followed.
This instrument has no power-on switch. An external switch or circ it-breaker shall be
included in the building installation as a disconnecting device. It shall be marked to indicate this
function, and it shall be in close proximity to the equipment within easy reach of the operator.
The switch or circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it
shall meet the relevant requirements of IEC 947–1 and IEC 947-3 (International
Electrotechnical Commission). The switch shall not be incorporated in the mains supply cord.
Furthermore, to provide protection against excessive energy being drawn from the mains
supply in case of a fault in the equipment, an overc rrent protection device shall be installed.
The Protective Conductor must be connected for safety reasons. Check that the power
cable has the proper Earth wire, and it is properly connected. It is not safe to operate this
unit without the Protective Conductor Terminal connected.
• Do not exceed voltage rating on the label located on the top of the instrument housing.
• Always disconnect power before changing signal and power connections.
• Do not use this instrument on a work bench without its case for safety reasons.
• Do not operate this instrument in flammable or explosive atmospheres.
• Do not expose this instrument to rain or moisture.
• Unit mounting should allow for adequate ventilation to ensure instrument does not exceed
operating temperature rating.
• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to minimize
electrical shock hazards.
EMC Considerations
• Whenever EMC is an issue, always use shielded cables.
• Never run signal and power wires in the same conduit.
• Use signal wire connections with twisted-pair cables.
• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist.
Fail re to follow all instr ctions and warnings may res lt in inj ry!

ABOUT TE METER
2.1 DESCRIPTION
The meter is a fully programmable ratemeter/ totalizer/ controller with six-digit resolution for
totalizing input pulses or rate measuring.
Alphanumeric display prompts make it easy to program with front-panel buttons. You may use a
personal computer to program the meter and monitor the display data using the RS-232 option.
You may store the program setup in the nonvolatile memory for recall upon demand or at power-
on.
The crystal timebase is electronically calibrated. There are no internal adjustments and
calibration is done without opening the case. Available options include field-installable dual-relay
option card, RS-232 and analog output cards.
2.2 FEATURES
The following is a list of features:
* 6-digit, single input
*NEMA4 / Type 4 Front Bezel
* Display of any engineering unit
* Front-panel scaling
* 0.5 z to 30 k z frequency inputs
* Signal conditioner standard for low level inputs
* DIP switch input selection
* Sensor excitation of 5, 8.2 and 12.4 Vdc
* Front-panel programmable as rate meter or totalizer
For more detailed information on meter features, refer to Tables 6-1 and 6-2.

2.3 MAIN BOARD
Table 2-1 details information for the S2, S3, and S4 jumpers. The S2 jumper has 3 possible
positions: A, B or C. Factory defaults are in bold and italics. Figure 2-1 illustrates where these
jumpers are located on the main board.

else is locked.
S2-B Everything is unlocked.
S2-C No lock-out, except for analog output
parameters.
Removed In the rate mode, meter shows "SPLO" and "SPHI" only (if
the relay option board is installed). In the totalizer mode,
meter shows the OFFSEt, SPLO and SPHI - everything
besides the relays are locked out. In either mode, the meter
stores changes in the nonvolatile memory automatically.

METER BUTTONS
RECALL Button
To initialize (hard reset) the meter, press the RECALL and RESET buttons simultaneously. The
meter momentarily shows the program revision letter and mode (totalizer or rate). The meter then
shows the last stored (saved) program in the active (volatile) memory.

£SET Button
Press this button to modify the flashing function, number value or decimal point (sub-menu only).
For example, press the £SET button to toggle between the totAL (totalizer) and rAte (rate)
modes. Once the correct function, number value or decimal point shows, press the MENU
button to enter the change into the active (volatile) memory.
¢ADV Button
Press this button to show the sub-menus and values for a selected menu item. The meter shows
values with left-most digit flashing. Press the ¢ADV button to move the flashing item from left to
right through the digital display and the £SET button to change the flashing item's value.
MENU Button
Press this button to show main menu items (refer to Section 6 for more information). The meter
does not show locked out (bypassed) items. The S2 and S3 jumpers determine lock out status.
RESET Button
Press this button to reset a latched alarm. Also, if you are in the totalizer mode, press this button
to reset the counter and begin counting from the offset. If you are in the setup menu (in either
mode) the meter returns to the run mode and makes measurements with the latest updated
menu items.
