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 energiz ed (“ON”
time) during a one-cycle time per iod. 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. DIS RPM Function:
Measures RPM on v ehicles with
Distributorless Ignition Systems (DIS) using an optional induc-
tive pickup. One range: 0 to 10,000 rpm.
