Equus 3340 - Automotive DMM (10 MegOhm / UL) - Manual (Page 9)

CONTROLS AND INDICATORS
1. DCV Function: Measures DC
volts. Auto-ranging from 0 to
600 volts (10 M
Ω impedance)
2. ACV Function: Measures AC
volts. Auto-ranging from 0 to
600 volts (10 M
Ω impedance)
3. Press SEL button (see item
19) to select desired function:
• Resistance Function :
Measures resistance. Auto
ranging from 0 to 40M
Ω
(40,000,000 Ω ).
• Continuity Function :
Tests for continuity be-
tween two points.
• Diode Function : For
testing diodes.
4. Frequency Function. Measures frequency. One range:
9.999Hz to 2MHz.
5. Pulse Width Function: Measures the length of time (in mil-
liseconds) that a solenoid or actuator is energized (“ON”
time) during a one-cycle time period. One range: 1 to 999
ms.
6. Duty Cycle Function Measures the percentage of time
that a solenoid or actuator is energized (“ON” time) during a
one-cycle time period. One range: 0.1 to 99.9%.
7. Temperature Function (Celcius): Measures temperature in
°C. Auto-ranging from -50°C to +400°C. (Optional “K-Type”
thermocouple required).
8. Temperature Function (Fahrenheit): Measures tempera-
ture in °F. Auto-ranging from -58°F to +752°F. (Optional “K-
Type” thermocouple required).
9. Press SEL button (see item 19) to select desired function:
• ACmA Function: Measures AC current in milliamps.
One range: 0 to 400 milliamps.
• DCmA Function: Measures DC current in milliamps.
One range: 0 to 400 milliamps.
10. 15A Function: Measures DC current. One range: 15Amps
(DC from 0 to 15 amperes). Unfused.
11. Clamp Current Function : Measures AC/DC cur-
rent; optional Clamp adapter required.
12. Battery Load Test Function: Two positions. Tests small bat-
teries; 1.5V, 9V.
