Measuring Insulation Resistance Insulation tests should only be performed on dead circuits. Check the fuse before testing. To measure insulation resis- tance, follow the steps below. 1. Insert test probes in the “⊕ “ and “ “ input terminals. 2. Turn the rotary switch to Insulation position. 3.
Measuring Frequency for ACV, ACmV and ACmA The meter measures the frequency of a voltage or current signal by counting the number of times the signal crosses a threshold level each second. To measure frequency, follow the steps below. 1. Turn the rotary switch to V, mV or mA position. 2.

Display MAX / MIN / AVG The “MIN/MAX/AVG“ mode records minimum and maximum input values. When the inputs go below the recorded minimum value or above the recorded maximum value, the meter beeps and records the new value. MIN/MAX/AVG mode can also calculate an average of maximum and minimum.

Auto Test and Manual Test The meter has both “AutoTest “ mode and Manual Test mode. ˙In the Auto Test mode, the meter compares the reading of AC and DC, and the bigger reading appears on the display. The meter beeps when the AC/DC mode has change. ˙In the Manual Test mode, you override “AutoTest “...
Auto Range and Manual Range The meter has both Auto Range mode and Manual Range mode. ˙ In the Auto Range mode, the meter selects the range with the best resolution. ˙ In the Manual Range mode, you select the range yourself. When you turn the meter on, it defaults to Auto Range mode and the “Range”...
Store and Recall You can store the reading on the display, and recall the reading on the display after. ˙To store the reading press the Store button. The data amount and “MEM” blink on the secondary display. ˙Each function has a separate memory space. Each memory space has the maximum 100 amounts.
Auto Power Off Wake-up the meter by switching rotor or pressing any button. Auto Backlight The backlight is automatically turned on at dark environment. BUZZER The meter beeps once for every valid key-press, and beeps twice for every invalid key-press. Power On Options Press button while turning the meter on from OFF position.
Battery and Fuse Replacement Refer to the following figure to replace fuse and the batteries : Caution ˙Use only a fuse with the amperage, interrupt, voltage, and speed rating specified. ˙ Fuse rating : 440mA,1000V fast blow fuse. ˙ Replace the batteries as soon as the low batteries indicator "...
Testing the fuse Test the fuse as described below. 1. Insert a test probe in the V, Ω, , Hz, °C input terminal. 2. Turn the rotary switch to Ω position, and press the Blue button to diode function. 3. Insert the probe in the mA input terminal. If the display reading is 0L, the fuse is bad and should be replaced.
