2. Step by Step Procedures: a. MEASURING DC VOLTS Application Notes When measuring DC Voltage of a battery, the most accurate reading can be attained by testing the battery under load. To accomplish this, follow steps 1 through 4 shown on page 10 and the following: • Connect the red test lead from the meter to the positive (+) terminal of the battery. • Connect the black test lead to the negative (-) terminal of the battery. • Reconnect power to the circuit and read the voltage on the 153.

b. MEASURING AC VOLTS CAUTION! Do not attempt to make a voltage measurement if a test lead is plugged in the A or µmA input jack. Instrument damage and/or personal injury may result. WARNING! Do not attempt to make a voltage measurement of more than 750V or of a voltage level that is unknown. Instrument set-up: Application Notes When measuring the AC voltage of a standard household outlet, remember that the small rectangular hole is hot, the larger rectangular hole is neutral and the round hole is ground.

d. MEASURING AC AMPS C. MEASURING DC AMPS CAUTION! Do not attempt to make a current measurement with the test leads connected in parallel with circuit to be tested. Test leads must be connected in series with the circuit. WARNING! Do not attempt to make a current measurement of circuits with more than 600V present. Instrument damage and /or personal injury may result.

Instrument damage and /or personal injury may result.
e. MEASURING RESISTANCE WARNING! Do not attempt to make resistance measurements with circuit energized. For best results, remove the resistor completely from the circuit before attempting to measure it. Application Notes When measuring resistance of a motor, make sure the power is disconnected prior to testing.

i. RECORD MODE The record mode saves minimum (MIN) and maximum (MAX) values measured for a series of reading. Activate the function as follows: 22 1. Depress the REC button on the 153. 2. The 153 will immediately start to record MIN/MAX values. REC will be on the LCD to show record mode has been activated. The reading on the LCD will be the actual reading. The 153 will give a confirmation beep every time a new value is recorded. 3.

F. MAINTENANCE 1. 2. 24 Battery Replacement: The 153 will display BAT when the two internal 1.5 Volt “AA” batteries need replacement. Batteries are replaced as follows: a. Disconnect and remove all test leads from live circuits and from the 153. b. Remove 153 from protective boot. c. Remove the three screws from back of housing. d. Carefully pull apart front and rear instrument housing. e. Remove old batteries and replace with new batteries. f.
