	ENERGY TESTERS FOR SEQUENTIAL BLASTING MACHINES
ET175-10 and ET225-10 Energy Tester

GENERAL INFORMATION

The REO ET175-10, ET225-10 and ET500-10 Energy Testers provide nominal test values of energy output (measured in percentage of rated energy) for each of the 10 circuits of REO Sequential Blasting Machines listed in the table below. A light Emitting Diode (LED) bar graph display allows the user to view the energy output of the REO Blasting Machine under test.

All REO Energy Testers have self test features and contain internal load resistance. Each tester is supplied with a cable to connect the tester to the blasting machine.

CHARACTERISTICS

Model	Applicable to REO Blasting Machine Models	Test Timing and Cables	Weight [Shipping Weight]	Size	Power Source (ALKALINE Batteries)
ET175-10	BM175 series	NO	2.8 lbs. (1.3 kg.) [5 lbs. (3 kg.)]	9.0 x 8.0 x 3.4 in. (22.9 x 20.3 x 8.6 cm.)	Two 9 volt Eveready 522 or equal
ET225-10	BM225 series	NO	2.8 lbs. (1.3 kg.) [5 lbs. (3 kg.)]	9.0 x 8.0 x 3.4 in. (22.9 x 20.3 x 8.6 cm.)	Two 9 volt Eveready 522 or equal

FEATURES

	Provides nominal test values of energy output (measured in percentae of rated energy) of REO Sequential Blasting Machines.
	Checks all ten blasting machine circuits with one firing.
	Accurate to within +/-5%.
	Self test function checks tester accuracy and tester batteries.
	Easy to operate.
	Automatic turn-on and shut-off.
	Fast battery change using readily available standard ALKALINE batteries.
	Rugged water and corrosion resistant ABS plastic case.
	Environmentally sealed to operate in most weather.

OPERATION

To test REO Sequential Blasting Machines using the ET175-10 or ET225-10 Energy Tester, connect the blasting machine to the tester using the EC15-2 Connecting Cable. Perform the self test function. Charge and fire the sequential blasting machine into the tester. The tester will turn on automatically and the FIRED light will come on if energy is present on any circuit. Rotate the CIRCUIT switch on the tester to each of the 10 circuits, noting the PERCENT OF RATED ENERGY indicated on the bar graph. The tester will shut off automatically after approximately thirty seconds.

SELF TESTING

The ET175-10 and ET225-10 perform an accuracy check and battery check of the tester when the TEST switch is held down and the CIRCUIT switch is rotated to each of the ten circuits. Illumination of the BAT OK and CAL OK LED bars indicates proper operation of the tester.

ENERGY TESTER FOR THE CD450-4J BLASTING MACHINE (ONLY)
	ET4J-1 Energy Tester

GENERAL INFORMATION

The ET4J-1 Energy Tester is a small convenient device used in the field to provide a Go/No-Go test of the energy output of the CD450-4J and CD450-4J-M blasting machines. The energy tester connects directly to the terminals of the blasting machine without the need for test leads or wires. A light emitting diode (LED) flashes briefly when the energy output of the blasting machine under test is equal to or greater than 100% rated energy. The energy tester is powered by the output of the blasting machine and does not contain batteries.

FEATURES

	Provides a field check of energy output of the blasting machine.
	Accurate to within +/-5%.
	Easy to operate.
	Contains no batteries.
	Rugged water and corrosion resistant nylon plastic case.
	Environmentally sealed to operate in most weather.
	Tab terminals connect directly to the blasting machine.
	Small size, 1.7 x 2.2 x 0.7 in. (4.3 x 5.6 x 1.8 cm.) - may be placed on a key ring or slips easily into shirt or jacket pocket.
	Lightweight, 1.3 oz. (0.04 kg.)
	Low cost.

OPERATION

Connect the two tab terminals on the tester to the terminals on the blasting machine by placing the tab under the shoulder of the blasting machine terminal and tightening securely. Observe the polarity indicated on the tester (RD tab to RED terminal and BK tab to BLACK terminal). Fire the blasting machine and watch the ENERGY OK light on the tester. The ENERGY OK light will flash briefly if the output energy of the blasting machine is 100% or greater. No flash indicates that the blasting machine energy output may be low, and the blasting machine should be removed from service and tested in a laboratory using established procedures utilizing an oscilloscope and a load resistor.

	ENERGY TESTERS FOR ALL SINGLE CIRCUIT BLASTING MACHINES
BT200, BT210 and BT250 Energy Tester

GENERAL INFORMATION

The REO BT200, BT210 and BT250 Energy Tester provide nominal test values of the energy output (measured in percentage of rated energy) of REO Single Circuit Blasting Machines listed in the table below. A light Emitting Diode (LED) bar graph display allows the user to view the energy output of the REO Blasting Machine under test. All models have a self test function and contain internal load resistance. Two 24" leads with spade connectors on each end are supplied with the tester.
