Measuring Function; Acv Function; Dcv Function; Low Ohm Function And Continuity Function - Amprobe AMB 45 Instruction Manual

V. MEASURING FUNCTIONS

1. ACV Function:

Turn function selector to voltage range. Connect black test lead to
Black terminal and red one to the Red terminal. Connect test lead
to the test circuit in parallel. Operator can hold the reading by
pressing the

2. DCV Function:

Turn function selector to voltage range. Connect black test lead to
Black terminal and red one to the Red terminal.
Press the
function. Connect test lead to the test circuit in parallel. One can
hold the reading by pressing the

3. Low Ohm Function and Continuity Function:

Turn function selector to Ohm range. Connect black test lead to
Black terminal and red one to the Red terminal. Connect test lead
to the test circuit in parallel. If the reading is less than 40 Ohm, the
continuity beeper will sound.
One may null the lead resistance (under 40 Ohm) by shorting the
test lead than press the
recorded a ZERO symbol will display on the LCD. Press
again to go back to normal operation. If the lead resistance is
great than 40Ω, the error beeping will sound. Because the test
current provided by the meter could reach 200mA, do not use this
range to test electronic component like diode, transistor or fuse.
Caution: Before measuring, verify the circuit is not live by voltage
function

4. MegaOhm Function:

Turn the function selector to the desired test voltage range. The
LCD will display "----" to indicate the tester is standing by. Connect
black test lead to Black terminal and red one to the Red terminal.
Connect test lead to the test circuit in parallel. One may take the
measuring under manual power mode or power lock mode:
