The instructions of this manual are for reference about the product. There may be
differences due to updates.
Please check our website (www.steren.com) to obtain the latest version of the
instruction manual.
• To avoid shock hazard, do the high voltage measures, carefully.
• Always disconnect the tested circuit before connecting testing leads.
• Before to use the range switch, disconnect the testing leads.
• Never operate this multimeter over the maximal indicated tolerance.
• When you use this multimeter on TV sets or interrupted power circuits, could have voltage pulses
with high amplitudes and may cause damages on the ammeter.
• Be careful when you manage with high voltages around 60VDC (V ---) or 30 VAC RMS (V~).
• Keep the fingers in back of the test barriers, during measuring.
• Unplug the test leads from all the electrical current before to open the ammeter.
• Never use the ammeter if the battery cover is not placed correctly.
• Only clean with a soft, damp cloth.
H I G H L I G H T S
• The auto range hook multi-tester has an ergonomic design.
• The ampere-meter function –using the hook- is very accurate and free of risks, with it you don't
require to peel the cable to measure.
• It can performs measuring of resistances, diodes, AC and DC voltage, AC amperage, and continuity.
• Very useful for students, technicians and engineers.
• It has a luminous display, hold, maximum value and auto range.
• Auto range.
• Audible continuity.
• Hold.
• Maximum value.
• Light for the hook and screen.

Hook arms
Place the current-carrying conductor (A~) in the middle of the arms of the
hook by pressing the hook button to open and releasing it to close it.
Inputs
This device has two entries that are protected against overload.
During use connect the black measuring lead into the COM
jack and the red lead to the INPUT one.
If you want to keep a measure on the screen for easy reading,
press the HOLD button. Press once more to return to the
measurement screen.

Current measurement
1. Turn the selector knob to the desired A~ position. Hook
arms will measure the amps of AC (~) that circulate through
the conductor.
2. When "0.L"appears on the LCD, it means that there is a
situation of overload. Select a higher range.
Voltage measurement
1. Place the selector knob on the V
the measuring leads.
2. Press the SEL button to select voltage of direct (DC) or
alternating (AC) current.
3. When "0.L"appears on the LCD, it means that there is a
situation of overload.
Resistance measurement
1. Place the selector knob on the Ω position and connect the measuring leads.
If the resistance being measured exceeds the maximum possible value, "0.L" will be displayed on
the LCD.
2. When making a resistance measurement in circuits, be careful that these are without power and
capacitors are fully discharged.
Diode measurement
To prevent electrical shock and/or equipment damage, disconnect the circuits and
discharge capacitors with high voltage before making measurements of diodes.
1. Set the selector knob in the
2. Press the SEL button to activate the diode test mode.
3.
will appear on screen.
4. The meter will show the approximate voltage of the diode.
Continuity measurement
1. Place the selector knob in the
2. Press the SEL button to activate the function of continuity.
3.
will appear on screen.
4.When the measurement result is less than 25 Ω, a continuous
tone will sound.
