SAFETY CONSIDERATIONS
This device is marked with the international Caution 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
Note ☞
the unit if damage is found.
T his instrument is a panel mount device protected in accordance with Class I of EN 61010
(115/230 AC power connections). 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 circuit-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 overcurrent protection device shall be installed.
Note ☞
•
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.

The Digital Panel Meter/Controller consists of a main assembly, signal conditioner and interface
options (if ordered) all housed in a 1/8 DIN case.
The main assembly consists of a main board and a display board which is permanently attached to it
at a 90 degree angle.
The main board provides mounting for the power supply, circuit components, and connectors for
plugging in the signal conditioner, optional analog card, and optional controller/communications
interface card (requires removal of a bypass push-on jumper).
The display board includes the analog-to-digital converter, the LED or LCD display and the push-on
jumper for programming the decimal points. Decimal point programming may also be done from the
main board connector (J1).

(_2000F, _2000G) AC RMS VOLTAGE, AC RMS CURRENT
17.1 GENERAL
The basic signal conditioner board is identified as a BSCF (_2000F or _9000F) for true-RMS voltage
input. The _2000 and _9000 prefix is determined by the main assembly board used with the BSCF
option board. When the BSCF board is configured differently, it is identified as a BSCF/G (_2000G or
_9000G), used for ac RMS current input.
17.2 BSCF: TRUE-RMS VOLTAGE SIGNAL CONDITIONER
Five full-scale ranges are provided in the _2000F and _9000F series.
See TRUE-RMS VOLTAGE INPUT tables Section 20. The true-RMS -to-DC converter is a monolithic
integrated circuit which computes the true-RMS value of complex input signals containing both AC
and DC components. It converts the true-RMS values to DC outputs or inputs with a crest factor of
2:1 or less.
17.3 BSCF/G: TRUE-RMS CURRENT SIGNAL CONDITIONER
Ten current ranges are provided in this series. Special full-scale (FS) ranges for other current
transformers can be provided on special order. See TRUE-RMS CURRENT INPUT tables in Section
21.
The true-RMS -to-DC converter is a monolithic integrated circuit which computes the true-RMS
value of complex input signals containing both AC and DC components. It converts the RMS values
to DC outputs or inputs with a minimum crest factor of 2:1 at full scale input.

TESTS & DIAGNOSTICS
The signal conditioner board BSCF is designed to function with a main assembly as a minimum
configuration. There is no provision for testing a signal conditioner board alone.
Signal input requirements for your configuration are identified in the specifications for the BSCF
signal conditioner.
Operating power and connections for your configuration are identified in the Main Assembly Section
of this manual.
Note:
If using Main Assembly _2000, refer to Section BQ20/BQ29.
If using Main Assembly _9000 refert to Section BQ90/BQ98
Inspect the panel meter for physical damage. If damage is apparent, resolve the damage with the
shipper or your supplier. Save all packing materials.
19.1 FUNCTIONAL ELECTRICAL TESTING
NOTE: Perform this test after your meter has been configured.
1. Short terminals 4, 5, and 6 on barrier strip (TB1).
2. Apply proper power for your configuration to terminals 1, 2 and 3 on barrier strip (TB1). Display
will read approximately zero (0000).

minimum reading on the display. The point where the digits reverse order (lower to higher) will
be the null.
3.
After adjusting the null, slowly adjust the internal zero-width (R25) pot to display the proper
reading (1% of full scale).
4.
Apply an input signal equal to 95% of the high end of the range selected and adjust the span pot
(S), R4, for the proper reading (95% of full scale).

25.1 UNPACKING & INSPECTION
Your Digital Panel Meter was systematically inspected and tested, then carefully packed before
shipment
Unpack the instrument and inspect for obvious shipping damage. Notify the freight carrier
immediately upon discovery of any shipping damage.
37
25.2 MECHANICAL INSTALLATION
Insure that the panel cutout dimensions are as shown on Figure 6.
Remove the lower printed circuit board edge connector, (if installed) J1, by pushing two molded
plastic tabs away from the connector body and pulling the connector off the printed circuit board.
Remove the printed circuit board edge connector, J2, if upper board output option was ordered.
Loosen two clamp screws on the rear of the case enough to rotate the two slide clamps.
Slide the two slide retainers toward the rear of the case and remove them.
From the front of the panel, insert the meter into the panel cutout.
Slide the slide retainers back into the case and push up tightly against the rear of the case.
Rotate the slide clamps back into their original position and tighten enough to hold the case in place.
Overtightening can break the clamps.
Install the lower printed circuit board edge connector, if supplied, by pushing it on to the printed
circuit board connections. Install the upper printed circuit board edge connector, if used.
