Installation Guide
“Multi-Sense” Model 260 Series
Multi-Range Differential Pressure Transducer
GENERAL INFORMATION
Every Model 260 has been calibrated and tested before shipment to guarantee
performance for all pressure ranges.
The Model 260 is available in four versions, which have field selectable range
capability via a slide switch. See four versions below:
MULTI-SENSE RANGE SPECIFICATIONS
The Model 260 is available in three field selectable output configurations. See three
versions below

SIMPLE 5-STEP SETUP INSTRUCTIONS - STEPS 2 - 5
Power On - LCD Display
Display momentarily toggles thru all existing setup parameters on initial power
up. Pressure is normally indicated on display. Units are either in inches of water
column (WC) MS1 & MS2, or Pascal (Pa) MS3 & MS4.

Media Compatibility
Model 260 transducers are designed to be used with air or
nonconducting gases.
Use with liquids or corrosive gases will damage the unit.
Environment
The operating temperature limits of the 260 are as follows:
Operating Temperature 32°F to 122°F (0°C to 50°C)
Compensated Temperature Range 32°F to 122°F (0°C to 50°C)
Model MS1 0.1”, 0.25”, 0.5” and 1.0” W.C. FS +/- 0.1”, 0.25”, 0.5” and 1.0” W.C. FS

STEP 3
:
Select Unidirectional
or Bi-directional mode.
**STEP 4:
Select Current (mA)
or Voltage 0-5, or
0-10 VDC output range.
*Step 2 will follow same
instructions for other inches of
water column and pascal
ranges.
* * Step 4 be sure to set mA/volt

JUMPER
ZERO AND SPAN ADjUSTMENT*
The unit may be recalibrated in the field using the push button zero/span.
Zero Adjustment:
1. With unit at zero differential pressure, push zero button for 5 seconds. Units
output and display will update.
Span Adjustment:
2. Apply full scale pressure (Note: Full scale value of largest range.). Press and hold
zero button for 5 seconds. Units output and display will update.
*Zero and Span points must be within 10% of factory setting.
