SPX POWER TEAM HT75, HT200 Operating Instructions Manual
MODEL C
IN-LINE HYDRAULIC FLOW TESTER
The 75 GPM (300l/min.) and 200 GPM (750 l/min.) inline hydraulic flow testers are compact, self-contained, portable
instruments for testing hydraulic systems in the shop or field. To simplify identification of the testers in this instruction
sheet, the two versions are identified by their English (GPM) flow capacities. Individual components are identified in
Figure 3.
SAFETY PRECAUTIONS
WARNING
●●
Before operating the pump, all hose connections must be tightened with the proper tools. Do not
overtighten. Connections should only be tightened securely and leak-free. Overtightening can cause
premature thread failure or can cause high pressure fittings to split at pressures lower than their rated
capacities.
●●
Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the pump.
Never attempt to grasp a leaking pressurized hose with your hands. The force of the escaping hydraulic
fluid could cause serious injury.
●●
Do not subject the hose to potential hazard such as fire, sharp surfaces, heavy impact or extreme heat or
cold. Do not allow the hose to kink, twist, curl or bend so tightly that the oil flow within the hose is
blocked or reduced. Periodically inspect the hose for wear because any of these conditions can damage
the hose and result in personal injury.
●●
Do not use the hose to move attached equipment. Stress may damage the hose and cause personal injury.
●●
Hose material and coupler seals must be compatible with the hydraulic fluid used. Hoses also must not
come in contact with corrosive materials such as creosote-impregnated objects and some paints. Consult
the manufacturer before painting a hose. Never paint the couplers. Hose deterioration due to corrosive
materials may result in personal injury.
SET-UP
Battery Replacement and Inspection
The testers are provided with two "C" size
batteries that are pre-installed at the factory.
To replace the batteries or inspect the unit
during trouble-shooting of either a 75 or 200
GPM tester, remove the three screws #16972
holding the digital display panel #352004 and
carefully lift the panel out of the opening. Do
not damage the circuit boards or components.
There is a "LO BAT." indicator on the LCD
display that shows when the batteries are low.
Battery life can be 500 hours. There is an
automatic shut off feature after 5 minutes and
the unit will have to be powered up after a time
out. Use only new "C" size alkaline batteries as
replacements. If the batteries have been jarred
out of their holder by impact, inspect the unit for
other possible damage.

Fittings
75 GPM Tester: The inlet and outlet ports (shown in Figure 2) are designed for SAE straight o-ring union adapters,
1-1/16-12 male thread by 3/4 NPSM female straight union. When the tester is not being used,
always insert the port plugs to protect the unit from damage or contamination.
200 GPM Tester: The inlet and outlet ports (shown in Figure 2) are designed for SAE Standard 1 1/2 inch, 4-bolt split
flange fittings. Flange bolts must be 1/2-13 UNC by 1 1/2 inch long SAE Grade 5 with spring
lockwashers, torqued at 55/65 ft. lbs. When the tester is not being used, always assemble the
cover plates to protect the tester from damage or contamination.

Operating Controls
Both testers have similar operating controls.
Refer to Figure 3.
POWER: Push this switch to turn the tester
ON; push to turn the tester OFF. When the
tester is not being used, the power switch
may be used to turn if off or it will
automatically shut off in five minutes.
DIGITAL DISPLAY: The display shows flow
and temperature readings, depending on the
setting of the FLOW/TEMP switch. An
analog bar at the bottom of the display
shows a real-time analog representation of
the portion of full-scale reading displayed.
LO BAT.: This indicator alerts the operator that
battery power is low, which can result in
false readings.
FLOW/TEMP: When the FLOW/TEMP switch
is held down, fluid temperature is displayed
on the meter temperature scale in either
degrees Fahrenheit and Celsius. When the
toggle switch is released, the meter returns
to its previous mode "flow". Flow is
displayed by default when the unit is on.
ENGLISH/METRIC: Units of flow or
temperature are alternately selected in
ENGLISH or METRIC whenever this switch
is pushed.
Hoses
1. Connect the pressure hose from the pump or
pressure line of the system to the tester INLET port.
2. Connect the return hose to the tester OUTLET port.
NOTE: If the hoses are connected wrong, the tester
gives flow readings but the pressure control valve
does not function. No damage to the unit occurs.
