Quick Start Installation Guide

1. Insert cable through Pressing Screw, Compression
Ring, Seal Grommet, and Sleeve as shown below.

2. Strip back 1-1/4” of outer sheathing, cut off any excess
wires, shield and ground. Strip off 1/4” insulation from
remaining two wires. It is not necessary or recommended

physically abused, moisture is not entering the housing, and that the wiring is sound.

If you feel that the output of the HH transmitter is not correct, calibration of the unit may be required.

Equipment required:
Pressure source
Accurate reference gauge
DC Milliamp Meter (accurate to .01 mA)
Small straight blade screwdriver
Calculator

Calibration - Transmitter
Adjustments to the transmitter are made via the "ZERO" and "SPAN" potentiometers. These two adjustments are non-interactive, meaning changing the
zero will not change the span. As general maintenance to the unit, a zero check is recommended at approximately 6 month intervals. If your unit is
calibrated at a compound range, you will not see 4.00 mA at atmospheric zero. As reference, you may use the following chart to determine if your unit may
require calibration (most common ranges are shown).

The output of a properly calibrated transmitter may be calculated by using the following formula:

NOTE: For pressure transmitters with compound ranges, the ranges must first be converted to all one type unit of measure. For example, a 30" Hg/0/35
psig unit may be considered to have a range of -14.7 psig-0-35 psig and a span of 49.7 psig (2.036" Hg = 1 psi). Be careful not to lose the (-) sign while
performing the calculation of the proper reading.

mA Output [ 16x [ ]]+4

NOTE: The transmitter should be wired in a complete loop at this point, or on a test bench. Although no interaction between zero and span occurs, when
making adjustments you should be as close to the top and bottom transmitter range as possible. This will ensure the best possible linearity in the final
signal output.

1. Expose the transmitter to a known zero reference point. If transmitter range starts at atmospheric zero, zero adjust at atmospheric zero. If transmitter
is a compound range, you should be as close to sensor zero as possible . You must calculate the expected mA signal (use formula above).

2. Remove cap from transmitter.

3. With your meter set to DC mA, connect the RED (Meter +) lead to the (TP +) terminal. Connect the BLACK (Meter - ) lead to the (TP -) terminal.

4. Adjust the transmitter ZERO potentiometer as shown, until you either see 4.00 mA if you are at atmospheric zero, or your expected mA signal for a
compound range.

5. Expose the transmitter to a know pressure at the top end of the range. Standard ranges may be turned down to a maximum of 50%.

6. Adjust the transmitter SPAN potentiometer, until you see 20 mA output.
