Using This Quick Start Manual

Use this Quick Start Manual to set up your Strain Meter and
begin operation. Information is provided on how to:
• Connect ac power

• Set basic options for operation

• Connect the sensor

• Scale the meter.

Features with         are for the “B” version which has three-
color programmable “Big” LED display - All segment
characters shown are for the “B” version.

IMPORTANT:

For complete information on all setup options,

please refer to the Operator’s Manual.

Mount the Unit

1. Cut a panel opening using the

dimensions shown to the right.

2. Position the unit in the opening,

making sure the front bezel is
flush with the panel.

3. Install retaining clips on both

sides of the meter and tighten against the panel.

Wiring

1. Remove the panel at the back of the unit.
2. Locate the TB1 connector.
3. Insert the correct wire in each terminal as shown in the

following figure and tighten the lockdown screws.

4. Tug gently on the wires to verify the connections.

Connect the Sensor

1. Locate the TB2 connector on the rear of the unit.
2. Attach the sensor wires and tighten the lockdown screws.

The diagram below shows the wiring for bridge sensors
with internal excitation. 

NOTE: 

Refer to the Operator’s Manual for setup requirements

for other sensor types.

Safety Consideration  

This device is marked with the international Caution symbol.

The instrument is a panel mount device protected in
accordance with Class I of EN61010-1 (AC units) and Class III
(DC units). Remember that the unit has no power-on switch.
Building installation should include a switch or circuit-breaker
that must be compliant to IEC 947-1 and 947-3.

SAFETY:

• 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.

EMC:

• 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 wire close to the instrument if

EMC problems persist.
