Installation and Set-up
Unpacking
Initial inspection should include checking for physical damage during 
shipping and obvious external damage to the product. 
Package	contents	are	defined	by	your	packing	list.	Each	Marshall	Loader	
is configured according to customer specifications. In your inspection, 
make certain that the contents of your shipment match the documentation 
provided by your packing list.
Place	unit	on	a	flat	smooth	surface	and	use	leveling	feet	(supplied)	and	a	
bubble level to ensure that the unit is level side-to-side and back-to-front.
Electrical Connections
The HM-1327 is equipped with an internal, digital, switching power supply, 
which allows it to be used with most power configurations throughout 
the world. The unit is supplied with an IEC electrical cord with a standard 
110V	plug.
The HM-1327 arrives ready for operation. Attach the supplied IEC electrical 
cord to the machine and plug into a standard wall receptacle for use in the 
United States. 
For locations other than the U.S., replace the supplied electrical cord with 
an IEC cord with the correct plug for your application. The supplied cord 
can also be used by cutting the standard plug from the cord and attaching 
the correct plug. 
Instrument Inputs (load cell/transducer connections)
The HM-1327 has 2 instrumentation inputs located on the back panel to ac-
commodate load cell/transducer connections. This feature allows you to set 
up and calibrate up to 2 different instruments, which the unit can quickly 
switch between for those needing to do multiple types of tests.
If you purchased load cells/transducers with your unit, they will either be 
mounted and calibrated, or in the case of multiple load cells/transducers, 
will be calibrated but not mounted. Additional load cells/transducers will 
be marked to indicate what input channel was used in the calibration; and, 
these load cells/transducers should be connected to the indicated inputs.
Third-party load cells/transducers, which are compatible, can also be used 
with the HM-1327. Compatible units will have an excitation voltage of 
0-10	volts	and	an	output	of	0-100	millivolts.	Prior	to	use	all	third-party	 
instrumentation	must	be	configured	and	calibrated	for	use.	Please	refer	to	
the Configuration and Calibration sections of this manual.
