Introduction The D99B Digital Clamp-On Meter is designed for professional electrician's, plant maintenance specialists and service technicians. Now technicians ca n work with added confidence, knowing they’re measuring with the superior accuracy of True RMS, increasing safety by illuminating dark work areas with a bright LCD Work Light, back light display and extending their measurement capabilities to 1000V AC/DC.
6. Peak Hold Push-Button: Used to capture the highest AC or DC inductive amp reading. C o n t rols and Indicators 2 7. Clamp Lever: Opens and closes current clamp jaw. 1 8. DC A Zero: Used to establish the “zero reference” when preparing to make DC amperage measurements. Magnetic fields in the iron core of the jaws will be interpreted as a current reading if not electronically compensated when measuring DC amps. 9.
5. AC: I n d i cates that alternating current (AC) amperage or voltage is being measured. 6. Minus: I n d i cates the value measured has a negative polarity. This will appear only while measuring DC amperage or voltage. 7. DC: I n d i cates that direct-current (DC) amperage or voltage is being measured. 8. mVA: I n d i cates that millivolts (mV), volts (V), or amps (A) is being displayed. 9. KΩ: I n d i cates that Kilohms, or ohms are being displayed. 10.
Measuring Voltage When taking voltage measurements your meter must be connected in parallel to the circuit, or circuit element, under test. When the 1000 V AC or DC function is selected the meter will automatically increase its range form 400 volts with (0.1 - volt resolution) to 1000 volts (with 1-volt resolution) when the voltage measured exceeds 400.
Maintenance Periodic service WARNING! Repair and service of this instrument is to be performed by qualified personnel only. Improper repair or service could result in physical degradation of the meter. This could alter the protection from electrical shock and personal injury this meter provides to the operator. Perform only those maintenance tasks that you are qualified to do.
Troubleshooting If I see this I should check for malfunction Specifications Then take this corrective action Debris on switch controls Move switch through all functions 3 to 4 times Instrument does not Battery voltage Replace low battery turn on Rotary switch position Ensure switch moves freely and is set to a Measurement limits AC Amperage DC Amperage AC Voltage DC Voltage Ohms Continuity 1000 Amps 1000 Amps 1000 Volts 1000 Volts 400 Kilohms < 40 ohms measurement position Instrument turns on
