3. The fuse may be replace at this time by removing it from its
holder. Replace only with a fuse of the same type and rating
specified.
4. Place the Battery Cover back into place and reinstall the
screw.
High Voltage Measurements
CAUTION:
Always observe the following rules and procedures
when making measurements in high voltage circuits. Voltages
greater than 40 VDC or 25 VAC may create a serious shock
hazard. Never use this meter on circuits with voltages higher
than 500 VAC RMS or VDC. Treat any unknown voltages as
though they were high voltages. DO NOT USE THIS METER
ON 480VAC POWER OR OTHER CIRCUITS THAT ARE
CATEGORY III PER UL-3111-1.
• For maximum safety, turn the equipment or voltage source
off before connecting the test leads. Make certain that no
capacitors in the circuit being tested remain charged to a high
voltage.
• Set the meter to Autorange. NEER CHANGE THE
POSITION OF THE FUNCTION SWITCH WITH POWER
APPLIED TO THE CIRCUIT.
• Touch the test probe tips to the circuit being measured and
take the required reading.
Using the Model 3526-B
Measuring AC and DC Voltage
1. Connect the black test lead to the COM jack.
2. Set the Function Switch to the V position
3. Select either DC or AC measurements by pressing the
DC/AC button. When AC is selected, the AC annunciator will
be visible on the display.
4. Connect the meter across the circuit to be measured.
5. Read the voltage on the display. For DC voltage
measurements, the Negative Sign annunciator indicates that
the Tip is negative with respect to the COM Jack.
Measuring AC and DC Current
1. Connect the black test lead to the COM jack.
2. Set the Function Switch to the mA position
3. Select either DC or AC measurements by pressing the
DC/AC button. When AC is selected, the AC annunciator will
be visible on the display.
4. With power to the circuit off, connect the test leads in
series with the circuit to be measured.
5. Apply power to the circuit and read the current on the
display. For DC current measurements, the Negative Sign
annunciator indicates that the Tip is negative with respect to
the COM Jack.
