Powering the Meter
The ST-4000 can be powered either by the internal rechargeable Ni-MH batteries or by use of
the included power supply/battery charger.
A) Using the external AC power supply: Make sure that the available AC line
voltage is 110-120V, 60 Hz. Connect the DC output plug from of the adapter /
charger to the DC receptacle on the bottom of the ST4000 meter.
B) Powering the meter with internal batteries: In order for the ST4000 meter to
operate from the internal batteries, a sufficient charge must exist on the batteries.
The recommended time to fully charge the batteries is 12 hours. Only use the
power supply / battery charger included with the meter. The batteries charge
whether the meter is switched on or off. The Red LED on the meter will illuminate
whenever the power supply / battery charger is attached and plugged into an
110VAC source.
Warning: Use Only The Power Supply / Battery Charger Supplied With The Meter.
Use Of Any Other Will Void Warranty and Can Cause Damage Or Injury.
