Description
With your purchase of the ARH5 you
now have the ability to take supply/
return temperature, %RH, wet bulb
and dew point measurements from
inside the duct or plenum.
Use the telescopic probe to take
measurements in hard to reach places.
Your ARH5 measures both
relative humidity and ambient
air temperature. It also calculates
dew point and wet bulb temperatures
automatically.
The ARH5 snaps directly onto
Fieldpiece HS series DMMs, Fieldpiece
Datalogger or HVAC Guide® System
Analyzer. For other meters, use
Fieldpiece ADLS2 test leads or the
AHDL1 handle adapter.
Use your ARH5 in combination with
the HVAC Guide and easily perform
Target Evaporator Exit Temperature
tests and get more reliable and
convenient Target Superheat
calculations.

How to Use
General Instructions
1. Remove vinyl slip cover from the
telescopic probe tip.
2.Connect directly ontoanyFieldpiece
HS multimeter. For most Fieldpiece
SC and LT meters, use Fieldpiece
ADLS2 test leads plugged into the
COM and VΩ jacks.
3. Select mVDC range on multimeter.
4.SetswitchpositionofARH5toTEMP,
WET BULB, DEW POINT, or %RH.
5. Read the measurement directly on
the multimeter display.
Protecting the Sensor
The ARH5 uses a precision
thermistor sensor. When not in use
it is best to protect this sensor with
the vinyl slip cover included with the
ARH5.
RCONE1 Probe Lock
For hands-free use, RCONE1 locks
your sensor probe in place inside the
duct. See Figure 1 on other side.
Diagnostic Tests
Wireless Return Wet Bulb
for Target Superheat
The ARH5 with a wireless transmitter
(ET2W, EH4W, or LT17AW) allows you
to monitor the return wet bulb while
you are at the condensor. Send this
real-timeWB measurement wirelessly
to the INPUT FORM of the HG3 HVAC
Guide® System Analyzer to calculate a
real-time target superheat.
1. Sync your transmitter with ARH5 to
the Return WB INPUT line in Super-
heat Test of the HG3 HVAC Guide.
2. Punch or drill a small 3/8" hole in the
returnplenum toinsert ARH5probe.
Press ENTER to lock in reading.
3. Input an outdoor dry bulb tempera-
ture manually with the ATH4 at the
condensor into the OD Dry Bulb
INPUT line in the Superheat Test of
the HVAC Guide.
4.PressOUTPUT on HVACGuidetosee
your target superheat calculations.
Target Evaporator Exit
Temp with the HVAC Guide
The ARH5 with Fieldpiece HVAC
Guide allows you to easily perform a
Target Evaporator Exit Temperature
(TEET) test to determine if the
evaporator is getting the optimum
airow.
1.SlideARH5ontothe top of the HVAC
Guide. Select TEET switch position.
2.Inthe INPUTFORM,highlight Return
DB.PressENTERto measure air tem-
perature going into the evaporator.
Drill a small 3/8" hole in the return
plenum and insert the ARH5 probe.
Set ARH5 switch position to TEMP.
Press ENTER to lock in reading. Take
measurements as close to the air
handler as possible. Seal any holes
before leaving the jobsite.
3.Inthe INPUTFORM,highlight Return
WB. Press ENTER to measure wet
bulb temperature going into the
evaporatorbyinserting ARH5probe
throughthe same holeatthe return.
Set ARH5 switch position to WET
BULB. Press ENTER to lock reading.
4. In the INPUT FORM, highlight Sup-
ply DB. Press ENTER to measure
air temperature coming out of the
evaporator. Punch or drill a small
3/8" hole in the supply plenum and
insert ARH5 probe in the center of
the plenum to take measurement.
Press ENTER to lock reading.
5. Press OUTPUT to view results.
Maintenance
Clean the exterior with a dry cloth.
Do not use liquid.
Battery Replacement
The batteries on the ARH5 must be
replaced when the LO BATT LED turns
red. Replace with one 9V battery.
Auto Power O
Your ARH5 powers o automatically
after approximately 15 minutes to
lengthen battery life.To disable "Auto
O," remove the grey rubber cover on
the front of ARH5 and slide the Auto
O switch to the left.
Limited Warranty
In the USA, this meter is warranted
against defects in material or
workmanship for one year from date
of purchase. Fieldpiece will replace or
repair the defective unit, at its option,
subject to verication of the defect.
This warranty does not apply to
defects resulting from abuse, neglect,
accident, unauthorized repair,
alteration, or unreasonable use of
the instrument.
Any implied warranties arising
from the sale of a Fieldpiece product,
including but not limited to implied
warranties of merchantability and
tness for a particular purpose, are
limited to the above. Fieldpiece shall
not be liable for loss of use of the
instrument or other incidental or
consequential damages, expenses, or
economic loss, or for any claim of such
damage, expenses, or economic loss.
State laws vary.The above limitations
or exclusions may not apply to you.
For Service
In the USA, call Fieldpiece
Instruments for one-price-x-all out of
warranty service pricing. Send check or
money order for the amount quoted.
Send the meter freight prepaid to
Fieldpiece Instruments. Send proof
of date and location of purchase for
in-warranty service. The meter will be
repaired or replaced, at the option of
Fieldpiece, and returned via least cost
transportation. Outside of the USA,
please visit www.eldpiece.com for
service contact information.
