Universal Electronic Ammeter
Digital ammeter is used to measure the AC current that goes the meter on its ring
circuit. It also can be used in other working condition that is on the purpose of
current measuring. The max value of the instantaneous conveyanoc current should
not ezceed 5A. The transforming rate of the can be set from 1/5A to 5000/5 with the
panel pushbutton. When the power sutting over, the class value set can be kept in
the meter and the meter can be working on this condition. The working power supply
input terminals(1-2) and the measuring signal connection terminals (3-4)are on the
back board of the meter and the display screen is on the font panel
Setting Of Current Transformer Ratio:
1. Press the key and then display screen will indicate the current value.
2. Press the ADD key (upwelling) or press the DOWN key (down welling) and
select the needed rate.
3. After select the rate, when press the set key, the display screen will be dark for
one time and the rate will be kept in the meter automatically.
4. Attention: When press the button, the time must exceed 3 minutes or the
operation will be of no effect.
Warning:
• A switch or circuit breaker must be connected between the network and the
auxiliary supply input of device
• Connected switch or circuit breaker must be in close proximity to the device
• Connected switch or circuit breaker must be marked as the disconnecting
device for the equipment
• The type of used fuse must be FF type and the current of the used fuse must
be 1A

Picoammeters
- Model 428-PROG Programmable Current Amplifier
The Model 428-PROG Programmable Current Amplifier converts fast, small currents to a voltage, which can be easily digitized or displayed by an oscilloscope, waveform analyzer, or data acquisitionsystem. It uses a sophisticated "feedback current" circuit to achieve both fast rise times and sub-picoamp noise. The gain of the Model 428-PROG is adjustable in decade increments from 103V/A to 1011V/A, with selectable rise times from 2μs to 300ms.

clamp on meter is a combination power analyzer, power quality logger, and clamp meter, and is ideal for monitoring electronic loads.
With the bright color power meter display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the Fluke 345 power analyzer is ideal for troubleshooting power quality on switching loads. Additionally, the Hall Effect clamp meter design makes measurement of dc current possible without the need to break the circuit with the power meter. The internal memory of the power analyzer enables long-term power quality logging for analysis of trends or intermittent problems.
Applications
Setup and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key power quality parameters
Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment
Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs
Load studies - Verify electrical system capacity before adding loads

Clamp-on current probes or "current clamps" enable the user to measure currents without breaking the electric circuit. Current clamps are designed with jaws that can be opened, placed around the conductor and clamped closed to form a magnetic loop around the conductor.
Current clamps offer a safe, cost-effective, simple and accurate way to take current measurements.
