Initial Power-Up and Check-Out
Note:
Each Baker Instrument Company Tester incorporates a supply ground
detection circuit. This circuit assures a positive grounding of the tester. If the
instrument is not properly ground , the OPEN GRN indication will light and
testing cannot proceed. Check the supply to the tester (broken ground, bad
extension cord, excessive ground to neutral voltage) and assure that a low
impedance ground is provided to the unit.
1.
Check that the On/Off switch is in the Off position.
2.
Connect the tester power cord to a 110-120 VAC outlet (or 220-240 VAC
outlet if appropriate). The tester will work on either 60 Hz or 50 Hz.
3.
Set the Output control to Min (fully counterclockwise).
4.
Turn the tester On/Off switch to On. Allow a brief period for CRT warm-
up. The following message should appear on the screen.
