If the reading is less than .2 AMPs, switch the red lead to the VΩmA(Center)
JackandsettheRangeSelectorSwitchtothe200mA setting.
5. When testing is complete, remove Test Leads and store with multimeter.
Resistance Measurements
Measure circuit resistance up to 2000K Ohms.
WARNING: NEVER measure resistance on circuit with voltage running through it.
1. Turn the Range Selector Switch to the 200 Ω position.
2. Plug the red Test Lead into the VΩmA(Center)Jack.PlugtheblackTest
LeadintotheCom(Bottom)Jack.SwitchtheMultimeterON.
Short the Test Leads together. The meter should read “0” Ohms.
3. Touch the exposed conductors with the tips of the Test Leads.
4. Read measurement.
If the reading is “1”, set the Range Selector Switch to the next higher Ohm
(Ω) position.
Transistor (hFE) Measurements
Test transistors to ensure proper function.
1. Turn the Range Selector Switch to the hFE position.
Switch the Multimeter ON.
2. Insert the transistor pins into the appropriate hFE jack (NPN or PNP)
according to the EBC (Emitter, Base, Collector) sequence.
3. The meter will show the approximate hFE value.
Diode Measurement
Test the voltage drop in diodes.
1. Turn the Range Selector Switch to the Diode ( ) position.
2. Plug the red Test Lead into the VΩmA(Center)Jack.PlugtheblackTest
LeadintotheCom(Bottom)Jack.SwitchtheMultimeterON.
3. Connect red probe to the anode of the diode and the black to the cathode.
4. The approximate forward voltage drop of the diode will be displayed in
mV. If the connection is reversed only “1” will be shown.
Battery Charge Measurement
Test the amount of charge left in batteries.
NOTE: This setting is for testing the charge of small 9V or 1.5V batteries only. Never
use this setting to test automotive or lead-acid batteries. The high current
could cause damage to the meter and/or cause severe personal injury. Use
the appropriate DC Voltage setting to test the open current voltage of such
batteries instead.
1. Turn the Range Selector Switch to the Battery ( ) position.
