Unsafe Voltage

To alert you to the presence of a potentially hazardous

voltage, when the Tester detects a voltage ≥ 30 V in

insulation test, ≥ 2 V in resistance, or a voltage overload

(OL), the Z symbol is displayed.

Battery Saver (Sleep Mode)

The Tester enters the “Sleep mode” and blanks the

display if there is no function change or button press for

10 minutes. This is done to conserve battery power. The

Tester comes out of Sleep mode when a key is pressed or

when the rotary switch is turned.

The 10 minute timer is disabled during any insulation

resistance or earth bond resistance measurement. The

time period starts immediately following any

measurement.

Rotary Switch Positions

Turn the Tester on by selecting any measurement

function. The Tester presents a standard display for that

function (range, measurement units, modifiers, etc.). Use

the blue button to select any rotary switch alternate

functions (labelled with blue letters). Rotary switch

selections are shown in Figure 1 and described in Table 2.
