Blasting Ohm Meter Reo BO1999-1

The REO BO1999-1 Blaster's Ohmmeter is a pocket-size SINGLE CIRCUIT model designed for general use. A nylon cord attached to the case allows the ohmmeter to hang from around the neck for convenient use. Long battery life, a rugged water resistant enclosure and heavy duty terminals provide the blaster with a dependable unit. This user-friendly digital ohmmeter speeds up circuit check-out and provides vital information necessary to assure a successful blast. 

The REO BO1999-1 Blaster's Ohmmeter provides nominal values of circuit resistance on a large easy-to-read digital display. Two terminals on the ohmmeter are provided for single circuit testing. The BO1999-1 Blaster's Ohmmeter measures resistances of 0 - 1999 ohms in one ohm increments, with an accuracy of +/- 1 ohm. The maximum test current is 2 milliamperes. The ohmmeter turns on automatically when a circuit is detected, and turns off automatically when the circuit is disconnected.

SPECIFICATIONS

OPERATIONAL TEST

This Operational Test must be performed before connecting a blasting circuit to the BO1999-1 Blaster's Ohmmeter:

1. Short the terminals on the ohmmeter with a short piece of wire.
2. The ohmmeter should turn on and indicate 000 (+/- 1)ohm.
3. If the battery is in need of replacement, BAT appears on the display.
4. Remove the short from the terminals on the ohmmeter. The ohmmeter should turn off and remain off.

GENERAL OPERATING PROCEDURE

Note: The following procedure is intended as a guide only, and each user must prepare and verify his own procedure consistent with Local, State, and Federal regulations. Complete Operating Instructions appear on the back of the BO1999-1 Blaster's Ohmmeter.

1. Perform the Operational Test.
2. Connect the blasting circuit to the terminals on the BO1999-1 Blaster's Ohmmeter.
3. Note the resistance displayed. Note: 1--- will be displayed if the resistance exceeds 1999 ohms.
4. Shunt the blasting circuit after testing.

CAUTION - USE OF THIS EQUIPMENT REQUIRES THAT THE OPERATOR HAS BEEN TRAINED AND CERTIFIED IN BLASTING TECHNIQUES.

WARNING: BATTERIES ALONE CAN FIRE ELECTRIC DETONATORS. KEEP BATTERIES AWAY FROM THE BLASTING CIRCUITS.

WARNING: KEEP THE BLASTING CIRCUITS SHUNTED WHEN NOT CONNECTED TO THE OHMMETER. MINIMIZE THE TIME THE BLASTING CIRCUITS ARE CONNECTED TO THE OHMMETER BY TAKING RESISTANCE VALUES QUICKLY.
