PREPARATION FOR USE AND INSTALLATION

 

Insert the battery cells, one at a time, in accordance with 

the polarity indications marked on both the battery cell and 

the battery holder. Insert the positive end of the battery 

cells first. 

After installing the cells, reinstall the instrument in its case 

and secure the ten screws. 

 

Power Up 

Plug the power cord into the R1L-BR1  front panel 

receptacle, and plug the other end into a standard AC outlet. 

For battery operation (with charged battery  cells), this step 

is omitted. Turn on the POWER rotary switch. Note that this 

switch turns on both line and battery power. 

 

Charging the Battery Cells 

Prior to battery operation, it is  recommended the R1L-BR1 

Microohm/Bond Meter be plugged into AC power for at least 

14 hours to charge the battery cells. To charge the battery 

cells, the Power Switch must be turned ON, and the Range 

Switch should be set to 20 

. With the Range Switch set to 

lower ranges, the charge rate decreases and the batteries 

will be discharged, especially on the 2 

mΩ

 range, even with 

no resistance connected to the instrument. (However, the 

discharge rate in this range will permit operation for at least 

14 hours with no resistance connected.) 

 

 

WARNING

 

ALTHOUGH THE FRONT PANEL IS NORMALLY GROUNDED 

VIA THE GROUND PIN OF THE POWER CABLE, IF THIS 

CONNECTION IS FAULTY AND IF THE HIGH SIDE OF THE 

POWER CABLE IS SHORTED TO THE PANEL, THE PANEL 

COULD POSSIBLY HAVE MAINS VOLTAGE ON IT; SO DO 

NOT TOUCH THE PANEL WHEN AC POWER IS 

CONNECTED.
